DIN HV Distribution
DIN HV fuses are partial-range high voltage currentlimiting fuses for use in distribution circuits from
2.3 - 38kV.
Their compact dimensions and non-venting characteristics
make them ideal for restricted enclosures. DIN HV fuses
have excellent short circuit performance and good low
overcurrent clearing capability. When used in combination
with fusible switches with fuse-activated trip feature, full
range clearing capability is achieved.
True full-range fuses are available in certain voltage and
amp ranges. Please contact Fusetek for more information.

Highly standardised DIN 43 625 dimensions.
Excellent short circuit performance. Ceramic bodies, pure silver elements.
'30' series fuses have temperature sensitive striker to protect against extended overload conditions, or external
overheating.
Sealed for indoor or outdoor use.(on Driescher products - use 'F' suffix on part number)
Striker pin can be used for visual indication or to actuate a 'trip all phase' mechanism.
High amp ratings available for larger installations. DRS factory paralleled configurations available.
Fully plated parts for cool running.
Installation Notes
1.
DIN fuses are partial range devices with a minimum interrupting rating. Care must be taken to ensure that anticipated currents below the fuse's minimum breaking current (m.b.c) are cleared by other devices. In this regard,
DIN fuses are similar to ANSI - 'E' rated fuses. Full range DIN fuses are available in limited voltage and amp
ranges. Please contact our offices for information.
2.
When DIN fuses are used in conjunction with a trip-all-phase-device, the minimum breaking capacity of the
switch or contactor must be equal to or greater than the m.b.c of the fuse.
3.
Voltage ranges specified are minimum and maximum voltages for safe operation. The normal +/-10% utility
tolerance on voltage must be taken into account when selecting a voltage range.
4.
When replacing fuses in the field, ensure that contact clips are clean and free of corrosion, dirt, grease etc...
Ensure that the fuse clips still have good tension. (if the fuse will spin easily in the fuse clips, the clips have lost
their tension and should be replaced)
5.
Fuses should be replaced in sets of three to avoid nuisance blowing caused by element damage.
Dimensions
All DIN fuse share common end fittings which fit into 45mm fuse clips. The only dimensional variables are the body
length (L) and body diameter (D). As this varies depending on voltage, amperage and other factors, please refer to the
tables in this section for D and L dimensions. Striker pins meet industry and DIN requirements for force/travel and can be
used for mechanical actuation or visual indication.
Transformer application
The fuse ratings recommended in the following tables have been chosen with the following conditions in mind:
!
!
!
Fuses must pass normal primary winding magnetising inrush currents: These are taken as 12x the normal full
load current(FLC) at .1 sec, and 25x FLC at .01 sec. Certain applications may require the use of a higher fuse
rating. Please contact FUSETEK with application details.
After a sustained power outage, the fuse must be able to withstand an overload of approximately 6 x FLC for 1
sec. and 3 x FLC for 10 sec.
The maximum voltage rating of the fuse must be equal to, or greater than the maximum line-to-line system
voltage.
Capacitor application
Refer to capacitor selection chart on page 44. Be sure to consider the switching options and proximity of other banks
when establishing a base FLC to apply.

E Rated Distribution fuses
FC series power fuses are current limiting partial-range
fuses usually used for fusing the primary windings of
medium voltage distribution transformers and associated
distribution circuits.
Their high degree of current limitation greatly reduces the
thermal and mechanical stresses imposed on system
components during a short circuit. They can be used
indoors or outdoors in a suitable enclosure and conform
to standard N.American dimensions.
E Rating Defined
100E or less:
Fuse must open in 300sec at 200-240% of
its rated current

General purpose 'E' rated characteristics.
Pure silver elements
Fully plated metal parts for cool running.
Excellent current limitation for substantial reduction of short
circuit stresses.
Blown fuse indicator pin for visual indication or mechanical actua
tion (except 2" body)
All D case (3" diam.) fuses can be supplied hermetically sealed
and without indicator for use in Hazardous location applications.
over 100E:
Fuse must open in 600sec. at 220-264% of
its rated current.
Thus, fuses with identical E ratings will
provide similar overload protection and coordination with transformer and other
protective devices.
Companion Products
Standoff insulators, fuse clips and bases. Please see accessories section in rear of this section. For other
ratings and designs, please contact Fusetek.
Retrofitting
Fusetek power fuses are dimensionally compatible with and interchangeable with other manufacturers' fuses
having the same dimensions and ratings. Standard 'E' rated characteristics ensure electrical equivalency.
Fuses should be replaced in sets of three to avoid nuiscance blowing caused by element damage.

E rated fuse Application
E rated fuses are used to isolate the voltage transformer from the supply in the event of a primary winding failure. Properly selected fuses will also operate quickly if there is a short circuit on the secondary side of the transformer. To provide
optimum protection without nuisance blowing, it is necessary to consider the following points:
!
!
!
The interrupting rating must be equal to or greater than the largest anticipated short circuit.
The fuse must pass the magnetising inrush to the primary windings without damage or operation. This inrush is
normally considered to be 12 times the primary FLC for 0.1 second.
The fuse's voltage rating must be equal to, or greater than the system voltage.

The striker pin system is connected by means of a high
resistance parallel conductor. After melting the main fuse
elements the striker pin will indicate the operation status
of the fuse and open a load break switch or actuate a
microswitch for remote indication.
The temperature limiting function
of the fuse striker pin
Design and construction
SIBA HV Fuse-links have parallel connected pure silver
fuse-elements. The design and method of production of
the elements ensures narrow tolerances of time-currentcharacteristics.
The fuse elements are wound on a ceramic support and
are attached to the silver plated connection caps by
means of spot-welding. The connection caps are fitted
inside the silver plated copper end caps by spot welding.
The copper end caps themselves are press-fitted onto
the porcelain tube which is glazed inside and outside.
The end caps are furthermore mechanically fixed to the
porcelain tube and additionally sealed by a durable
elastic sealing medium. This sealing method has been
proven over many decades of positive field experience
and ensures tightness against ingress of humidity.
Striker pin
SIBA HV Fuse-links are available with striker pins of the
force:
• 80 N (Part No. 30 … 13 for basic-type) and
• 120 N (Part No. 30 … 14 for variant-type)
The characteristics of both striker pins corresponds to
IEC 60282-1, VDE 0670 Part 4 and are of the energycategory “medium”.
SIBA HV Fuse-links up to and including 160 A with a
striker pin of 80 N are equipped with an integrated
temperature limiter as standard. The temperature limiter
is fitted inside the striker pin system. The SIBA striker pin
system therefore has the following functions:
• thermal protection of adjacent equipment, especially
SF6 Insulated switchgear
• limitation of failure current at the overload region
• improved properties for the switch-fuse combinations
according IEC 60420
The integrated temperature limiter avoids inadmissible
high temperatures – no matter for whatever reason they
are generated – in gas-insulated switchgear or narrow
switchgear enclosures. By means of a melting activator
temperatures inside the fuse link enclosure are limited to
below approx. 100°C. This design especially considers
continuity of current supply for the end user for as long
as possible. The system reacts in such a way that short
time overloads do not cause the fuse to interrupt the
circuit unnecessarily. Only when inadmissible values are
exceedes the fuse will open the switch via the striker pin.
Higher temperatures on plastic fuse enclosures in SF6insulated switchgear can be caused by:
• selection of a fuse rating too low for transformer
protection
• fuses are loaded with fault currents below the minimum
operating current
• deterioration of fuse links caused by transient fault
currents (e.g. lightning strike)
• transformer faults currents (e.g. winding short-current)
• overloading of the fuse when loaded with currents as
described in IEC 420 Test Duty 3
• additional temperatures rise because of poor clip fitting
Fuse-links with integrated temperature limiter are compatible with standard Fuse links. All coordination schedules can be used.
Further information on our temperature limiter, design,
construction, can be obtained from our website.

GERMAN DIN STANDARD – GENERAL PURPOSE
According IEC 60 282-1 and VDE 0670 Part
4, a General-Purpose-Fuse interrupts fault
currents between the rated breaking current
and the current which causes melting within
one hour. The protection range of the SIBAVS-Protector extends this basic demand.
The minimum breaking current is about 1.5
times the rated current. In combination with
the temperature released striker pin a full
range protection is possible. Additional feature is the small powerloss of the VS-Protector. It is up to 40 % smaller than the
standard DIN-fuse.
The dimensions of the VS-Protector are
VS-Protector for the overload and
short-circuit range
according to DIN 43625. The rated voltages
12 and 24 kV and also the available current
ratings allow protection of transformers up
to 630 kVA.
The function of the VS-Protector is comparable to a typical Back up Fuse link. The
melting elements of pure silver are wound
inside onto a ceramic support. A short
section in the center of the fuse is designed
as a “Heat chamber”. Inside this chamber
the elements are made of silver-alloy. They
generate a certain level of temperature at
overloads. As a result the fuses interrupt at
low fault-currents without ageing.

DRIWISA™ HIGH VOLTAGE CURRENT-LIMITING
FUSES HIGH INTERRUPTING CAPACITY
INDOOR AND OUTDOOR USE
Overview
DRIWISA™ high voltage, current-limiting fuses are devices with a high interrupting capacity to protect high voltage systems against short-circuits.
They are selective elements for individual operation, with very well defined time-current characteristics, ideal for protection of transformers, motors, capacitors
banks, cables, lines and other high voltage equipment installed in switchgear and distribution networks.
The accumulated experience for almost 30 years of DRIESCHER Y WITTJOHANN, S.A. in Mexico with the support of FRITZ DRIESCHER GmbH in Germany,
has permitted the use of the electrical principles and phenomena involved during the fusing and arcing process, which are the basis to design and manufacture
the fuses with a high dependability and quality level. The company has also characterized herself for the support and instructing capacity for its customers,
making sure, that every technical problem the client has, is solved to a complete satisfaction.
DRIWISA™ high voltage, current-limiting fuses are designed and manufactured according to international standards. This means, that the mechanical and
dimensional features, such as the tube diameters and lenghts and the force of the tripping pin of the fuses are according to these standards. The electrical
features and specifications, such as the maximum interrupting current (I1), the critical interrupting current (I2), and the minimum interrupting current (I3) have
been satisfactorily tested in internationally recognized labotarories.
DRIWISA™ fuses are built within a service range from 2.4 to 38 kV. The DRS series is built for indoor use, while the DRS series (with "F" end-code) is used in
outdoor applications, even for installation in tropical and very humid climates, for system frecuencies from 40 to 60 Hz.
These fuses can be installed on special fuse-holders, non-load isolator switches and load-break disconnecting switches, thus giving an adecuate protection
against the dangerous thermic and dynamic stresses during a short-circuit (refer to the corresponding sections in the catalogue).
Fuses from the DRK series, having tapped end-caps, may be used for capacitor protection, being screwed directly onto the capacitor bushings.

DRIWISA™ HIGH VOLTAGE CURRENT-LIMITING
FUSES HIGH INTERRUPTING CAPACITY
INDOOR AND OUTDOOR USE
Currrent-limiting:
When protecting equipment such as transformers, motors, capacitors, cables or lines with DRIWISA™ fuses the currents flowing in case of a short-circuit are
considerably reduced, due to the current-limiting characteristic of the fuses (refer to Figure 5 in the Fuse Manual).
Fuses not sensitive to transformer or motor inrush currents:
Due to their relatively slow time-current characteristic, DRIWISA™ fuses installed to protect transformers or motors do not exhibit premature fusion or
degradation of the fuse-elements if selected according to the recommendations given in Technical Bulletins 201 and 202.
Permanently fixed fuse-elements:
The fuse-elements are wound on special element-holders with dented borders to ensure they are held in place permanently, thus avoiding dislocation and
preventing internal short-circuits, which would provoke a degradation of the fuses characteristics.
Tripping device with excellent operation characteristics:
DRIWISA™ fuses are equipped with a tripping device (striker pin) acting through a stored-energy mechanism in a precompressed spring, which trips with a
force of 120 N (120 kp), large enough to even open disconnecting switches which have not been operated during an extended period of time, thus presenting
friction and resistance due to dust, dirt and corrosion (refer to Figure 3 in the Fuse Manual).
High interrupting capacity:
DRIWISA™ fuses display a high interrupting capacity which permits the interruption of very high short-circuit currents (refer to Figure 6 in the Fuse Manual).
Selectivity and protection coordination:
Maintaining a ratio of 1:1.6 between fuses installed in series the right coordination and protection selectivity is achieved, which makes isolation and faultdetection easy. Unnecessary power interruptions can be avoided (refer to section "Selection" in the Fuse Manual).
Special sealing of fuses for outdoor service:
The sealing of the fuses is accomplished by the use of special epoxic resins to avoid moisture penetration. For outdoor service fuses a special weld is used to
perfectly seal against humidity.
Repair with factory warranty:
Due to their special design and construction DRIWISA™ fuses are the only ones that permit repairing in the factory, guaranteeing their original characteristics,
when the porcelain tube has not been damaged. This means an interesting economic saving feature and an alternative for recicling materials, as a contribution
to the environment protection.
Immediate availability:
Due to the large distribution network set up by DRIESCHER Y WITTJOHANN S.A. with authorized representatives located at strategic locations, DRIWISA™
fuses are made available on short notice, thus representing a great advantage for the immediate replacement of used elements.
Technical support:
DRIESCHER Y WITTJOHANN, S.A. offers her customers immediate technical support and advise when needed as for the proper selection of the right fuse for
each particular case, to protect transformers, motors, capacitors, distribution lines and any other high voltage equipment, editing technical bulletins with
complementary information on the fuses and on subjects related to their application, selection and maintenance.

TABLE 1
DRIWISA™ current-limiting fuses manufacturing program
DESIGN AND CONSTRUCTION:
The fuse design ponders on a several compartments system or series of arcing chambers, where the voltaic arc produced by the fusion and/or evaporation of
the fuse link is quenched.
Fuse links, formed by one or several 99.9 % pure silver strips, are uniformly wound over a star shaped strip-holder (star-shaped body) built out of steatite (a
ceramic material with great mechanical and thermal resistance), in agreement to every particular fuse design.
Due to its tooth edges design, the star-shaped body guarantees the fuse link safe and firm position. Together the star-shaped body and the fuse links are put
into a porcelain tube which sets up the fuse cilindric body, thus forming the series of arcing chambers (Figure 1).
In every one of these arcing chambers a part of the voltaic arc produced by the fusion and/or evaporation of the fuse link when a short-circuit occurs, is started,
developed and quenched. This process is described farther on. Therefore the fusion and interrupting process is carried out without the influence of external
factors.
Fuse links have a group of precision holes regularly spaced lengthwise, calibrated in agreement to each fuse feature, which constitutes a reduction in the
conduction cross-section. When a short-circuit current is flowing, it is in these zones where the elements fusion is produced and the voltaic arc during the first
part of the current wave is established. Type and number of parallel connected silver strips depend of the fuse rated current.

INDOOR AND OUTDOOR USE
According to the above mentioned, the uniform distribution of the voltaic arc and the resulting voltage of the fuse operation is assured. The high interrupting
capacity and the rated current wide range available, are mainly the result of these design features which allow the dissipation of the thermic energy generated
during the fusion and/or evaporation process in a uniformly distributed shape.
The fuse is filled with silica sand of specific granulometry and formulation, thus providing the proper environment for voltaic arc cooling and quenching through
the absorption and dissipation of the generated heat and condensation and solidification of the evaporated metal.

DRIWISA™ fuse before and after a short-circuit current interruption
Figure 2 shows a fuse after it has operated, where the melted strip elements in each chamber, uniformly distributed and parts of intact strips in the transition
points from one chamber to another can be seen.
The voltaic arc starts in the middle of each chamber where the thicker melted elements are found. They become thinner at the same time as they get closer to
the walls that separate one chamber from another, showing the interrupting characteristic in a distributed shape. Intact strip residues at the transition points
indicate the availability of an additional fuse interrupting capacity.
Fuse ends have silver coated electrolitic copper caps which are connected inside to the silver strips ends.
DRS and DRS...F types have a mechanic indicator which operates through a stored energy system in a preloaded spring mechanism with a striker pin that
emerges by one fuse end when the fuse blows out with a force of 120 N (12 Kg-force) and a travel of 35 mm.
In accordance with IEC standard classifications, the striker pin features of DRIWISA™ fuses place it as heavy duty (strong) type. Exhaustive tests have
demonstrated that it is capable of activating the DRIWISA™ disconnector switch quick make mechanisms even in critical conditions, such as a blocked
mechanism after a long period of time without operation, overcoming friction and resistance caused by the presence of dust, dirtiness, rust on hinges or lack of
lubrication. Figure 3 shows the mechanic indicator force-displacement characteristic.

DRIWISA™ fuse before and after a short-circuit current interruption
DRIWISA™ fuses work satisfactorily in any mounting position.
In every case epoxy-resin is used as a seal between the caps and the porcelain tube, to assure great resistance and long life sealing, waterproof and resistant to
most severe and extreme atmospheric conditions. For outdoor fuses, additionally a special welding between the caps and porcelain tube is used to offer an
optimum sealing.
At facilities with high degree of humidity, coastal, tropic or rainy zones, it is recommended to use outdoor fuses (type DRS...F) even when installed in interiors.
In regard to their electrical, dimensional and mechanical characteristics (diameters, lenghts, striker pin operation force, etc) DRIWISA™ fuses are manufactured
in accordance with international standards. For further details, consult the catalog Selection Guide (Section I) which contains the specifications and mechanical
and electrical data.
OPERATION:
OPERATION PRINCIPLE:
When a short-circuit condition occurs in an electric network, very appreciable thermic and dynamic effects are produced because of the high current values. The
interruption of these currents in the shortest time possible is very important, since the damages produced by overheating of conducting parts and by dynamic
stresses must be avoided or at least minimized.
Current-limiting and high interrupting capacity fuses are used as protection against short-circuit currents. The importance falls on the current-limiting effect,
which is the fuse capacity to interrupt a short-circuit current before it reaches its maximum peak value by limiting the value of ID to the breaking current or fusion
current IS . This is considerably less than the non-limited short-circuit current (prospective current) Ik" shown in Figure 4 with a dotted line and which
corresponds to the short-circuit current available at the point where the fault occurs.
Figure 4 shows the current and voltage behavior during a short-circuit current and the interrupting process.

Short-circuit current interrupting process in a current-limiting fuse
When the short-circuit begins, a minimum resistance opposes the flow of the current ID thus increasing at the same time the current Ik" and starting the
temperature elevation process in the fuse link (silver strips). When they reach the IS value, (fuse breaking current or fusion current) the fuse link melts and/or
evaporates and interrupts the circuits on several points, with multiple voltaic arcs showing up, whose length increases quickly with the material melting and/or
evaporating. Voltage increases rapidly from the moment of the fusion, reaching a maximum (interruption voltage) and the current is limited to the IS value. At
this moment a current decreasing process begins.
The limiting process is therefore the result of the insertion of the voltaic arcs resistance at several points from the fusion.
When arcs turn cold by effect of the surrounding sand consequently the conductivity is reduced and therefore, the resistance to the current flow increases
quickly. The current decreases gradually at the same time as the voltage. Near to the next pass through voltage zero, the voltaic arcs are extinguished and the
current remains totally interrupted. The described events occur within the first half cycle of the short-circuit current, meaning, in less than 8 to 10 milliseconds.
Formation of multiple voltaic arcs at the fuse length as a consecuence of DRIWISA™ fuses special design gives a uniform voltage distribution as result as well
as of and the great amount of energy (heat) produced during this short process, thus preventing the posibility of arc reignition.

Figure 5 shows DRIWISA™ current-limiting fuses characteristic indicating the let-through current maximum value ID (equal to the fusion current IS) with regard
to the prospective short-circuit current rms value ( Ik" ) for fuses from 6 to 500 A.
FIGURE 5
Maximum let-through current ID refered to the short-circuit prospective current Ik"
Line A-A' represents the maximum asymmetrical peak current that would show up in the circuit for every value of the symmetrical short-circuit prospective
current Ik" (rms value) in case a fuse would not exist.
The value of 1.8 x √2 corresponds to the maximum asymmetric value possible in the network for the first phase to interrupt, which represents the most critical
condition.
The lines corresponding to every fuse rated current show the maximum let-through current ID (which corresponds to the fusion current IS ) in relation to the
short-circuit prospective current Ik" (rms value).
For example, for a short-circuit prospective current of Ik" = 20 kA rms a let-through current ID = 1.8 x √2 x 20 kA = 50.9 kA peak would show in case a currentlimiting fuse would not exist. With a 32 A fuse this value is limited to only ID = IS = 4 kApeak within an operation time lower than 10 milliseconds (figure 7).
It is obvious that for low currents, for which the fusion time is long (including times over one cycle) the fuse does not act as a current-limiting fuse. Fuses will
show their current-limiting characteristic only from a current value where IDpeak is the same as IS. Starting at this level of current, the fuse will operate as a
current-limiting fuse (on the right side of the A-A' line in Figure 5).
The point where the line corresponding to IS of every fuse meets with the A-A' straight line, defines over the abscissa (X axis) the short-circuit current value as of
which the fuse operates as current-limiting. If the short-circuit current is lower, the fuse will not operate as a current-limiting one. For example, a 75A fuse will
operate as a current-limiting fuse as of approximately 2000 A of short-circuit.

RATED CURRENT (In):
The fuse rated current is the maximum current value that the fuse can conduct for indefinite time without reaching fusion and the one to generate an energy
such as the fuse can satisfactorily dissipate.
INTERRUPTING CAPACITY ( I1 ) (MAXIMUM INTERRUPTING CURRENT) :
The interrupting capacity (maximum interrupting current) I1 corresponds to the maximum short-circuit current that a fuse is capable of interrupting safely lying of
the neighborhood of several tenths of kA.
The interrupting capacity (maximum interrupting current) of DRIWISA™ fuses lies above the short-circuit currents usually available in electric networks.
Nevertheless it is recommended to verify the short-circuit current of the network when selecting a fuse.
The corresponding Selection Guides specify the maximum interrupting current and the interrupting capacity (MVA) for each type of fuse.
When the short-circuit power instead of the short-circuit current is specified, the ratio between them is deduced from the following formula:
Pshort-circuit = kVnet x kAshort-circuit x √3
MINIMUM INTERRUPTING CURRENT ( I3 ):
For values above In fusion times are very long and they decrease at the same time the current increases (Figure 6). In this range, heat dissipation capacity is
lower than the amount of heat generated inside. Therefore severe thermic stresses that may damage the fuse show up.
While the current increases, the fusion times are reduced, until a point is reached where the fusion occurs in a relatively short time, before thermic stresses and
damages to the fuse show up.
This current value is called the minimum interrupting current I3 and corresponds to the lower limit of current ranges that the fuse may satisfactorily interrupt.
FIGURE 6
Characteristic time-current curves for current-limiting fuses
Considering the above, time-current curves define a minimum interrupting current value ( I3 ) for each fuse type, below which an operation during a long period
of time is not recommended, since the current (overcurrent) does not have the magnitude high enough to produce fusion, but produces an excessive heating,
modifying the fuse links characteristics and producing thermic damages to the fuse body.
Therefore current-limiting fuses must not operate during long periods of time in the range of currents higher than the rated one ( In ) and lower to the minimum
interrupting current ( I3 ). However, in case of high currents ( higher to I3 ), that is within the short-circuit current range, the fuse operation is quick, defined and
predictible.
Figure 7 shows - in a graphic way - the different fuse operation zones and the conditions and limitations of each one.

Current-limiting fuses operation zones
Even though the fusion process is based on known physical principles and laws, when currents higher than In (overcurrents) show up during a time greater than
the reply time corresponding to I3 (tI3) or overcurrents of an intermittent type, there are difficulties in analysing and evaluating, because the behavior of the fuse
will depend on their magnitude and duration, as well as on the periods between these overcurrents, during which the fuse is able to return to a normal regime or
even to the cool condition.
If an overcurrent lasts a relatively long time and then stops, it can start fusion or reach the amalgamating condition with a rise in temperature because of energy
disipation during that period of time, changing in a significant way the fuse links characteristics. When later found subject to a new overcurrent regime or shortcircuit, the fuses will react in a different way as to the standard characteristic, producing first heatings or inexplicable interruptions and then a reaction
completely out of specification.
Consulting Figures 8 and 9 which show DRIWISA™ fuses time-current characteristic for the range of available rated currents in the manufacturing program, it
can be seen that the minimum interrupting current I3 (begining at the dotted line) for fuses with rated currents up to 63 A, is about 2.5 times higher than the fuse
rated current In . For rated currents larger than 63 A, the minimum interrupting current I3 is about 3 times the fuse rated current In, while for fuse rated currents
of 200 A and higher it corresponds to 4 times the rated current In.
RATED CURRENT SELECTION ( In ):
To avoid fuse operation within the overload range, the fuse rated current In is selected with an overdimensioned factor according to the equipment to protect,
which for example, in case of transformers lies between 1.6 and 2 times the circuit rated current. This way the fuse will be able to hold up with the magnetization
currents (inrush) and even if the transformer works within an overload regime, the fuse will not be exposed to such, due to the transformer higher thermic
capacity.
Appling this factor it will be possible to coordinate protection with other devices such as overcurrent relays, phase fault relays and protection elements on the
low voltage side, for example, fuses, thermomagnetic switches and other protections. Any current higher than I3, will be interrupted in a time no longer than 10
to 100 sec., according to the corresponding curve in Figures 8 and 9. For further information regarding transformer protection, refer to Technical Bulletin 201.
In regard to motor protection similar criteria are followed as described in Technical Bulletin 202, while capacitor protection is explained in Bulletin 203. For
overhead lines or underground cables it is reccomended to consult Bulletin 204.
TIME-CURRENT CHARACTERISTIC CURVES:

The tight tolerance in the fuse links lineal resistance and a strict quality assurance during the manufacturing process guarantee the characteristic curves
repeatibility.
Applying the overdimensioning factors and following the selection criteria in agreement with the different applications, there is little probability of overloading of
the fuse due to values lying above the rated current In to occur. However, in accordance with the knowledge of the net, if the risk probability is high, the
protection against overloads with currents larger than In but smaller than I3 during longer periods of time, should be provided by other means, such as
overcurrent relays connected to disconnection devices like switches or load-break disconnectors. For further details consult Technical Bulletin 302.
The oscillogram in Figure 11 shows the current characteristic performance and the voltage during a short-circuit interruption when a DRIWISA™ fuse type
DRS07/100-A2 with 12 kV rated voltage and 100 A rated current subjected to a short-circuit prospective current of Ik" = 63 kA rms is used.
The current-limiting effect can be deduced when observing that the maximum let-through current ID reaches a value of 15 kA peak corresponding to the fuse
fusion current IS , while the current that would have flown in the test circuit, replacing the fuse by a very low resistance conductor, would have reached a value
of 160.5 kA peak of the maximum asymmetrical peak current ( 1.8 x √2 x 63 A = 160.5 kA peak ).

OPERATION VOLTAGE ( Vn ):
The interrupting voltage or maneuver voltage generated during the arc extintion process, by inserting its high resistance and interrupting currents with a high
grade of inductance, is of special interest. Transient voltage during interruption must not exceed the insulation levels, usually coordinated in the network, since it
would provoke trouble mainly at the insulation of other components of the system, among others, at arresters placed on the line side. For this reason it is
important to use fuses with a rated voltage in agreement to the network voltage.
When using a fuse with less rated voltage in regard to the network voltage, problems to manage the voltage gradients will present, while using one with greater
rated voltage and consequently greater interruption voltage would cause a higher voltage gradient and consequently would create problems with the insulation
of other equipments in the system.
In multiple tests accomplished on DRIWISA™ fuses, the highest arc interruption voltage value found was of VU = 1.95 x √2 x VO = 2.76 x VO. This value is
considerably lower than those admitted by the standards (Table 2). Consequently, using fuses with rated voltages corresponding to network voltages, there is no
danger of provoking damages to the insulation of equipments connected to the load side, such as transformers, switches, substations, motors, etc. and avoiding
the arresters operation.
Table 2 lists the maximum arc interruption voltages admissible for high voltage fuses in accordance with international standards.

Maximum interruption voltage levels corresponding to the fuses rated voltage
DRIWISA™ fuses can be installed in three-phase networks whose service voltage does not exceed the fuse rated voltage. In one-phase networks the service
voltage must not be larger as 87% of the fuse rated voltage.
In other cases, fuse voltage selection must be such that the maximum interruption voltage (maneuver voltage) does not exceed the maximum voltages
established for the network (see Table 2).
APPLICATION WITH LOAD-BREAK DISCONNECTOR SWITCHES:
Using current-limiting fuses in combination with DRIWISA™ load-break disconnector switches, three-phase group operated with automatic and auxilliary trip
type LDTP, an economical and reliable connection and disconnection equipment is obtained.
In this case, minimum interrupting current values I3 may be considered lower ( from 1.8 to 2 times the fuse rated current In ). This is because of the premature
reply of the fuse striker pin, which in case of being used within load-break switches, provokes the tripping of the auxilliary mechanism and the simultaneous
opening of the three phases.

This way, when the first fuse acts, the disconnector switch operates opening the three poles, interrupting the current of the remaining phases that otherwise
would not have been interrupted but until the respectives fuses had acted maybe after several minutes or even hours, subjecting them to thermic stresses and
eventually producing damages to the protected equipment, also preventing a two-phase operation.
During the interruption of the remaining phases, the disconnector switch is not subject to large stresses because it just has to interrupt the rated load current of
the net voltage. In case that some of the other fuses would have started its fusion process, the disconnector switch will only have to deal with the small arcing
currents, thus remaining the fault disconnected and isolated.
In accordance with international standards, for the extreme condition of operating an unfused load-break switch an inductive power factor = 0.7 (cos φ = 0.7) is
specified. However, under short-circuit conditions at the transformer secundary terminals for instance, the value of cos f can be considerably lower, around 0.1.
Nevertheless when using a combination of fuses with a DRIWISA™ load-break switch disconnector, this last will just have to disconnect a much lower current
value due to the fuse current-limiting characteristic and with a power factor within its rated range, thanks to the high arc resistance of the fuse.
The utilization of fuses with striker pin in combination with load-break disconnector switches is recommended for its excellent features and behavior in case of
short-circuits at transformer secundary terminals.
This is the reason why many electric utilities around the world use and specify DRIWISA™ fuses with striker pin to operate within three-pole load-break
disconnector switches.
ADVANTAGES:
DRIWISA™ high interrupting capacity fuses guarantee a safe operation even for networks with a high short-circuit power.
Their current-limiting characteristic guarantees the reduction to a minimum of damages to the network and other equipments, that could originate because of
dangerous short-circuit currents dynamic and thermic effects.
Because of their relatively slow time-current characteristic, DRIWISA™ fuses used for transformer or motor protection do not show untimely fusion or fuse link
degradation if they are selected accordingt to the corresponding recommendations.
Fuses are sealed with epoxy resin to achieve great airtightness against humidity. For outdoor use fuses, a special welding between covers and caps is used in
order to offer a perfect protection against humidity.
Costs savings when the same fuses can be used in networks that have increased their short-circuit power.
DRIWISA™ fuses are recyclable and can be repaired with the original manufacturer guarantee by DRIESCHER Y WITTJOHANN, S.A.
DRIWISA™ fuses are manufactured in a wide range of operation currents and voltages to satisfy any necessity.
DRIWISA™ fuses are standardized in dimensions which makes the selection and replacement easy.
USE AND HANDLING PRECAUTIONS:
The following precautions must be taken into consideration when handling and using fuses:
- Water or humidity must not penetrate into the fuse, since the high temperatures that are reached when fusion takes place, will provoke the abrupt
generation of steam which causes the possibility of an explosion.
- Handling fuses with precaution, avoid breakage of the porcelain and the caps to get dented. If this happens, DO NOT USE THE FUSE, AS SERIOUS
RISK OF DAMAGES, HAZARDS OR INJURIES MAY OCCUR.
- Fuse copper caps are silver-plated to give them excellent conductivity and assure a good electric contact. DO NOT USE SANDPAPER OR FIBER TO
CLEAN THE CAPS IF THEY ARE DIRTY OR IF THEY HAVE TURNED BLACK, since this does not affect their electric conductivity features. Use a soft
cloth lightly wet with silver cleaning solution not containing any abrasive or agressive materials.
- Do not place metallic or metallized labels on the fuse body, since this may provoke an external flashover, as the dielectric distance along the air between
the caps is reduced.
- Fuse repair or rehabilitation must be done by skilled and responsible personnel; they must know about the operation principles and electrical phenomena,
and must have the technical ability, skills, equipment and technology to perform these activities. DRIWISA™ fuses can be repaired renewing their original
guarantee only by DRIESCHER Y WITTJOHANN, S.A. or they can be exchanged through Authorized Distributors or Service Centers.
- When buying or repairing fuses, consider the equipment, installations and personnel value they are protecting and remember that "THE CHEAPEST MAY
BE THE MOST EXPENSIVE" . Entrust your installations and personal safety to DRIWISA™ fuses.
- Even when just one fuse had operated after a short-circuit condition in a three-phase system, it is necessary and very advisable to replace the set of three
fuses since the unblown fuses may have inside damage if the fusion process (pre-arcing) had begun, this will cause later problems such as inexplicable
temperature rise or undesirable interruption. This recommendation is also contained in international standards.

TRANSPORTATION AND STORAGE:
During transport of DRIWISA™ fuses avoid strikes that can break or crack the porcelain fuse body or dent the caps. In case of indoor service fuses, do not allow
them to get wet or to stay in humid enviroments to avoid the penetration of moist.
When receiving new fuses, inspect them before storage, informing the Authorized Distributor or the factory of any problem.
Fuse storage must be done in a closed, cool and dry place. Do not store them in places where there are vibrations, moist or pollution.
Keep the fuses inside their original package on a shelf in order to be safe against falling and do not stack more than 5 boxes.
MAINTENANCE:
DRIWISA™ high voltage and high interrupting capacity fuses do not require any maintenance.
However it is recommended that after the fuse operation in a three-phase system, to replace the set of three, even when only one fuse has blown, since the
others could have been subjected to thermic stresses that may caused them damages and then cause later problems such as inexplicable temperature rise or
unexpected interruptions without any suitable cause.
In cases of high or prolonged overloading in the circuit protected by fuses, it is recommended these being verified as to its features in factory or with any
Authorized Distributor or Service Center besides to have been subjected to overcurrent, they may have suffered irreversible thermic damages that modify and
demote its original characteristics.
It is advisable in all cases to be equipped with a set of at least 3 fuses as spare for emergency cases. These fuses must be of the same characteristics to those
installed. Keep them following the instructions given in the section "transportation and storage".
Fuse copper caps are silver-plated to give them excellent conductivity and assure a good electric contact. Do not use sandpaper or fiber to clean the caps if they
are dirty or if they have turned black, since this does not affect their electric conductivity features. Use a soft cloth lightly wet with silver cleaning solution not
containing any abrasive or agressive materials.
Do not place metallic or metallized labels on the fuse body, since this may provoke an external flashover, as the dielectric distance along the air between the
caps is reduced.
Fuse repair or rehabilitation must be done by skilled and responsible personnel; they must know about the operation principles and electrical phenomenon, and
must have the technical ability, skills, equipment and technology to perform these activities. DRIWISA™ fuses can be repaired renewing their original guarantee

INSTALLATION AND/OR REPLACEMENT:
It is recommended to follow the following instructions when placing or replacing fuses:
A)
ACCOMPLISH THE SAFETY PREPARATIONS:
1)
Use special pliers for the handling of high voltage fuses ( brand DRIWISA™ type DW-018)
2)
Use insulating gloves properly guaranteed for use in high voltage.
3)
Use a headpiece made of insulating material.
4)
Have ready cable, hook stick and equipment to connect to ground.

Have ready a sand bed where fuses can be placed.
6)
In front of the equipment which contains the fuses, place an insulating platform for high voltage or a wood platform with an insulating rug and stay
above it all the time the operation lasts, even more if the environment is humid.
7)
If working in branch circuits or remote substations, place placards in the main substation or switch where it let knows that someone is working there
"DO NOT CONNECT" " MEN WORKING..." .
B)
THINK FIRST AND THEN ACT, remember that when working with high voltage, the FIRST MISTAKE may be THE LAST ONE.
8)
9)
Disconnect the high voltage supply:
8.1)
Be sure that the main load-break disconnector or main switch is open. If not, open it.
8.2)
Open the non load-break isolator.
8.3)
Connect the ground switch ( in case of having this kind of equipment).
Open the door cabinet; stay strategically where the door does not hit you, nor get projections from inside.

DRIWISA™ HIGH VOLTAGE CURRENT-LIMITING
FUSES HIGH INTERRUPTING CAPACITY
INDOOR AND OUTDOOR USE
PRECAUTION:
FUSES MAY REACH HIGH TEMPERATURES SO THAT WHEN THE CABINET DOOR IS OPENED, THEY CAN
RECEIVE A THERMAL IMPACT, THAT MAY CRASH AND/OR MAKE EXPLODE THE PORCELAIN TUBE. THEREFORE
LET THE FRESH AIR ENTER SLOWLY.
10)
Connect the ground cable; use the correct size of cable and a hook stick.
Connect it first to the substation or switchgear ground bus or grounding structures and then to the phases (in case of not having a ground switch
integrated to the equipment).
11)
Find out and determine the cause that made the fuse blow, it can be a short-circuit or an overload. Eliminate the trouble, remove the remains and
make a general cleaning.
12)
Verify the condition of equipment and installations.
13)
Inspect the new fuses and make sure they do not show maltreatment, cracks or fissures, check that the porcelain tube is not broken, grooved or
scratched, nor the caps are dented or plunged. If some things mentioned before would happen, do not use them since their use is very risky.
14)
Fuse copper caps are silver-plated to give them excellent conductivity and assure a good electric contact. DO NOT USE SANDPAPER OR FIBER
TO CLEAN THE CAPS IF THEY ARE DIRTY OR IF THEY HAVE TURNED BLACK, since this does not affect their electric conductivity
features. Use a soft cloth lightly wet with silver cleaning solution not containing any abrasive or agressive materials.
Verify that the fuse striker pin is brought back and is in its place.
Do not place metallic or metallized labels on the fuse body, since this may provoke an external flashover, as the dielectric distance along the air
between the caps is reduced.
15)
Remove the old fuses with pliers DW-018 and replace them for DRIWISA™ fuses of the same characteristics: Type, rated voltage and rated current.
Never use fuses of different brands in the same circuit or different type, rated voltage or current even if they're of the same brand, since their
characteristics are not the same.
In three-phase systems it is recommended to replace the set of three fuses even when only one had blown since the others may be damaged and
cause problems later.
PRECAUTION:
FUSES MAY STAY HOT, PLACE THEM ON THE SAND BED, LETTING ENOUGH TIME PASS BEFORE TOUCHING
THEM WITH BARE HANDS.
16)
If the fuses are installed in load-break disconnectors, verify the operation of the auxiliary trip mechanism.
17)
Place the new fuses carefully, making sure the clips assemblies make the proper contact with the fuse caps. When inserting the fuses in the clip
assemblies, make pressure on the ends and not on the middle of the fuse. Do not hit the fuse.
18)
Remove all the tools that have been used and verify that are complete and it has not stayed behind anything inside the cabinet.
19)
Disconnect the grounding switch or the ground connections, wherever it is the case.
20)
Close the cabinet door, connect the non-load isolator switch and connect the high voltage supply.
21)
Replace damaged fuses for new fuses, of the same rated voltage and current. In some cases, when the fuse operation is because of overloads, verify
the load calculations and if necessary ask for three new fuses at the adecuate rated current according to the new calculation.
DRIWISA™ fuses can be repaired including their original guarantee only by DRIESCHER Y WITTJOHANN, S.A. or they can be exchanged through
Authorized Distributors or Service Centers.
Fuse repair or rehabilitation must be done by skilled and responsible personnel; they must know about the operation principles and electric
phenomena, and must have the technical ability, skills, equipment and technology to perform these activities. Do not expose installations, equipments
and own security.
SELECTION:
When selecting current-limiting fuses always consider the following factors:
-
Network rated voltage
Interrupting capacity
Installation altitude
Fuse rated current, according to application
Coordination with other protections
Type of service (indoor or outdoor)
Dimensions
Availability of spare, service and technical assistance
Security and reliability : always use DRIWISA™ fuses

CONTENTS
Recommendations for protection with current-limiting fuses: TRANSFORMERS.
Recommendations for protection with current-limiting fuses: MOTORS.
Recommendations for protection with current-limiting fuses: CAPACITORS.
Recommendations for protection with current-limiting fuses: OVERHEAD LINES AND CABLE FEEDERS.
Considerations and criteria for the parallel-connection of fuses (two-per phase arrangement).
Equivalency between DRIWISA™ fuses and american fuses type "R" and "E".
Shunt-trip coil for electrical remote control.
Selection of non-load break isolator switches and load-break disconnector switches with fuse-holders.
Selectivity and coordination of protections is reached by keeping a rate of 1 : 1.6 between fuse rated currents, being the smallest the one connected closest to
the load and the biggest the one connected from the supply side, assuring this way that the smallest blow first, interrupting and isolating the fault.
In case of transformer protection, to establish selectivity and coordination with protections on the low voltage side it is necessary to refer to the high voltage
fuses time-current characteristic curves and to the curves of the devices and/or fuses of the low voltage side (for further information refer to Technical Bulletin
201).
Sometimes, for big transformer protection, it is necessary to appeal to a two-per-phase fuse arrangement to reach the required rated current value. For these
cases it is recommended to consult Technical Bulletin 205 before deciding on this arrangement.
For motor protection it is required to know the starting time, the maximum starting current, and the motor startings frecuency to select the correct fuse. It is
recommended to consult Technical Bulletin 202.
Capacitor and capacitor-bank protection invest special importance, because of the increasing use they have to keep the power factor within the acceptable limits
and the relative rank of difficulty for its adequate protection, since connection currents reach, in many cases, levels very close to those of short-circuit. For
further information consult Technical Bulletin 203.
For fuse selection for overhead lines and cable feeders, the selection criteria are described in Technical Bulletin 204, considering that it must be done in function
of the transversal section and the admissible current in the conductor.
In the fuse selection for networks and circuits with high probabilities of long duration or high overloadings which require therefore of fuses with high currents
rates, it is reminded that these must be used for protection against short-circuits and not for protection against overloading. Requeriments for specific
arrangements in networks have to be calculated in detail by the customer to control and/or verify the continuous load regime over the fuses, the interruption
current, and the fuse interrupting capacity.
All data corresponding to voltage, current, interrupting capacity given in this Manual and/or Selection Guides of Catalogs, Technical Bulletins, etc., are refered to
installation heights up to 1000 m over sea level and an enviroment temperature up to 40 ° C.
In any way, once selected the correct fuse for its application, consider the installation altitude correction factors included in Table 3, in the fuse rated current as
in the interrupting capacity and rated voltage reduction. If it is calculated with the correction by altitude in the rated current, do not use the temperature rising
correction and viceversa.
In some cases, a temperature correction factor should be additionally considered, in those cases in which the fuses are installed inside of cabinets or
switchboards with little ventilation and/or high temperatures, in accordance with Table 4.
When there exist several sizes of fuses for a specific rate of current, it is advisable to consider the future installation growth (greater rated current) or the
increase of short-circuit capacity, this means to verify if for the selected fuse size exist larger rated currents or interrupting capacities, in such a way that when
selecting them it is chosen a size that allows to increase the capacity, by means of just changing fuses by others of greater current or interrupting capacity when
this growth requires it.
Bulletin 206 establishes equivalency criteria between american fuses curves type "R" y "E" and DRIWISA™ fuses curves.
Fuses must have a rated voltage equal or greater to the system highest voltage between phases, when they are used in three-phase systems with neutral firmly
grounded or with neutral connected through an impedance or resistance.
When using fuses in systems with isolated neutral (not grounded), the rated voltage should be at least 1.15 times the system highest voltage between phases.
When fuses are used in one-phase systems, its rated voltage should be at least 1.15 times greater than the voltage between phase and ground.

TCCF
2.4/4.8kV Capacitor fuses
TCCF fuses are current-limiting, partial range fuse designed to provide
short circuit protection for capacitors. The primary application of
these fuses is for the individual unit fusing of three phase capacitors
in metal enclosed equipments. They are non-indicating and nondisconnecting.
!
!
!
Direct stud-mounting on 1/2-13 capacitor studs eliminates
seperate holder.
replaces Westinghouse and CGE fuses
Adapters are available to convert to other stud threads(pg49)

TFCF 600V Capacitor fuses
TFCF fuses are current limiting fuses designed for unit fusing of
600v (or less) capacitors. They are threaded for M12 metric
capacitor bushings, but may be adapted to 3/8 or 1/2" UNC
threads with the adapters shown on page 48.
!
Metric threaded for direct screw on mounting to metric
capacitor
studs.
!
Excellent short circuit performance.
!
Fully plated metal parts for cooler running.
TFCF fuses should be selected at 250-300% of the nominal
capacitor full load current or next nearest size up. If capacitor is
installed in close proximity to other capacitor banks, or is
switched frequently, select higher amp fuses within this range.

Fuse Selection chart for Capacitors
Applicable for all current limiting fuses - high and low voltage. Use dotted line for single phase and star connections,
solid line for delta connections. Above 100A, curves are identical.
For auto-switching, or switching in close proximity to other capacitor banks, multiply capacitor FLA x 1.6 before using
scale at bottom. Read up from capacitor FLA scale at bottom to intersection of appropriate curve (star or delta). Fuse
rating is whatever band intersection occurs in. Read fuse rating on left scale.

Transformer application
The fuse ratings recommended in the following tables have been chosen with the following conditions in mind:
!
!
!
Fuses must pass normal primary winding magnetising inrush currents: These are taken as 12x the normal full
load current(FLC) at .1 sec, and 25x FLC at .01 sec. Certain applications may require a higher amp rating than
recommended. Please contact Fusetek with application details.
After a sustained power outage, the fuse must be able to withstand an overload of approximately 6 x FLC for 1
sec. and 3 x FLC for 10 sec.
The maximum voltage rating of the fuse must be equal to, or greater than the maximum line-to-line system
voltage including utility tolerances.

DRIWISA™ load-break switches are used to connect or
disconnect high voltage distribution circuits under load
conditions. The fused version of the switch provides
automatic 3 phase disconnect if any of the fuses operates. Operation of the fused and non-fused versions can
also be initiated through a shunt trip or manual operation.

Description
MR series fuses are current-limiting backup fuses designed to protect medium voltage motors and their associated
control. They have standardised dimensions and are fully interchangeable with other fuses of the same type and rating. Blown fuse indication is standard on all types. The design of the striker travel and force
'R' Rating Defined
meets standard requirements for mechanical actuation.
Features
!
!
!
!
Integral indicating pin for visual or mechanical operation
2.5kV and 5.5kV fuses can be hermetically sealed and supplied
without indicator for use in hazardous location application.
fully plated metal parts for low contact resistance
standard 'R' ratings ensure interchangeability.
Installation notes
The 'R' rating for a fuse is established
by dividing the 20-35 second melt
current of the fuse by 100.
In this way, fuses having the same 'R'
rating will melt at the same current
level at 20s - thus ensuring identical
motor starting capability and coordination with the overload relays.
When replacing motor starting fuses, always match the 'R' rating - not
the amp rating - to maintain identical co-ordination and motor starting
capability. Fusetek MR fuses can replace any manufacturers' motor fuse having the same dimensions. Ensure that fuse
clips still have good tension and clean all contact surfaces before re-installing fuses. The striker pin should be pointing
up when installing fuses.
Fuses should be replaced in sets of three to avoid nuisance blowing caused by element damage.
Motor Circuits
There are motor/fuse selection charts in each section. To use these fuse charts it is necessary to know the starting
current and run-up time of the motor. For starting conditions not shown, please contact Fusetek.
!
!
!
Select appropriate run-up time (6 or 15 seconds)
Read down to appropriate starting current range.
Read across to find 'R' rating.

Application
PT fuses are used to isolate the voltage (or PT) transformer from the supply in the event of a primary winding failure.
Properly selected fuses will also operate quickly if there is a short circuit on the secondary side of the transformer. To
provide optimum protection without nuisance blowing, it is necessary to consider the following points:
!
The interrupting rating must be equal to or greater than the largest anticipated short circuit.
The fuse must pass the magnetising inrush to the primary windings without damage or operation. This inrush is
normally considered to be 12 times the primary FLC for 0.1 second.
The fuse's voltage rating must be equal to, or greater than the system voltage.

Medium Voltage Fuses
2400 - 25,500 VAC
■
Current Limiting
Current limiting “E” and “R”
rated fuses are equipped with
a mechanical indicator or
striker pin that protrudes
through the fuse cap upon
operation of the fuse. This
provides visual identification
of a blown fuse and can be
used as a trigger for external
devices.
GENERAL INFORMATION
The terms “Medium Voltage” and “high voltage” have been
used interchangeably by many people to describe fuses
operating above 600 volts. Technically speaking, “medium
voltage” fuses are those intended for the voltage range from
2,400 to 38,000 VAC. “High voltage fuses are for circuits
carrying voltages greater than 38,000 VAC.
“E” Rated fuses are considered to be general purpose fuses
and can be used to protect against low and high values of
fault current. “R” rated fuses are designed for back-up protection. They must be used in series with other devices, such
as motor overload relays, in order to achieve both overload
and short circuit protection.
Littelfuse now offers a complete selection of “E” and “R”
rated medium voltage fuses for the protection of transformers, potential transformers, feeders, and motor circuits.
Single, double, and triple barrel designs are available to
cover a wide range of current, voltage, and interrupting
ratings. Conventional ferrule type, clip lock, and bolt-in
mounting configurations are now available for virtually any
application. Hermetically sealed fuses for use in hazardous
environments are also offered.
Contact the factory or your local Littelfuse representative for
additional fuse ratings or custom mounting configurations.
Medium voltage fuses are not intended to provide overload
protection in the same sense as fuses rated 600 volts or
less. Medium voltage fuse current ratings do not have the
same meanings as the ampere ratings of low voltage fuses.
All medium voltage fuses are limited in their ability to interrupt low value overcurrents, especially those between 100%
and 200% of the fuse’s continuous current rating. They are
designed to carry their rated current without exceeding the
temperature rise permitted by NEMA and ANSI standards.
Additional application data can be found in the Fuse
Application section of the POWR-GARD Products
catalog (PF101).
24 Hour Emergency Service is available.

R Rated Medium Voltage Fuses
Current Limiting
FEATURES
CHARACTERISTICS
“R” rated fuses provide required short-circuit protection for
medium voltage motors, motor controllers and associated
circuitry. These components have limited ability to absorb the
energy of large short circuit currents. Medium voltage motor
controllers contain overload relays which provide both overload protection and locked rotor protection to the motor. The
controllers are also intended to interrupt low value short circuits within the capability of the motor controller. This protects the medium voltage fuse from sustained overcurrents
which are less than their minimum interrupting rating.
Voltage Rating: 2,400 volts – 15,500 volts
Current Range: 2R – 36R

Bolt-in mounting configurations
NEMA Standards for “R” rated medium voltage power fuses
require that they operate within 15-35 seconds when subjected to an rms current 100 times the “R” rating. For example, a fuse with a 2R rating will open within 15 to 35 seconds
on an applied current of 2 x 100 = 200 amperes.

E Rated Medium Voltage Fuses
Current Limiting
“E” Rated fuses have time current characteristics designed
to provide current limiting protection for power transformers,
potential transformers, power centers, feeder centers, and
unit sub stations. When properly applied, they can protect
against high and low value fault currents.
NEMA Standards for “E” rated medium voltage fuses require
that fuses rated 100E or less open within 300 seconds (5
minutes) when subjected to an RMS value of 200-240% of
the fuse’s continuous current rating; and fuses with an “E”
rating larger than 100E must open within 600 seconds (10
minutes) when subjected to an rms current of 220-240% of
the fuse’s continuous current rating. These values establish
one point on the time-current curve.
CHARACTERISTICS
Voltage Rating: 2,400 volts – 38,000 volts
Current Range: 10E – 600E
OPTIONS

Hermetically Sealed for use in hazardous locations
(add “S” suffix to part number)
Clip-lock (CL) and bolt-in styles available.
Application Note:
Since these fuses are used for the protection of general
purpose circuits which may contain transformers, motors,
and other equipment producing inrush and/or overload currents, fuses should generally be rated at 140% of the normal
full load current, and circuits should be analyzed to ensure
that system load currents will not exceed the current rating
of the fuse.

Clip Lock Design
The clip lock type designs ensures a positive contact between
the fuse and the connection cam. The fuse’s clip lock tab slides
in between the clip casting and the cam to prevent the fuse from
slipping or blowing out of the holder. This positive contact
improves heat dissipation and allows fuses to run cooler.

E Rated Potential Transformer Fuses
Current Limiting
Potential Transformer (PT) fuses are current limiting fuses
with high interrupting ratings designed for the protection of
potential transformers.
CHARACTERISTICS
Voltage Rating: 600VAC – 25,500 VAC
Current Range: 1/2E – 10E
Application Note:
When applying fuses for the protection of transformers,
the magnetizing current inrush must be considered. The
characteristics of the inrush, which can be matched with
a fuse’s time-current curve, should be available from the
transformer manufacturer.
