Although initially a British design, the Class C fuse was the original Canadian HRC fuse. Introduced at a time when
the only choices were low performance one-time or renewable fuses, the Class C fuse was quickly specified by the
Canadian pulp, paper, and mining industry, and is still in widespread use in these industries today.
n Provides Type 2 protection for IEC and NEMA control.
n Fully plated parts for low contact resistance and cool running.
n Notched tags for easy fuse replacement. (2-100A)

These tables assume that the secondary side of
the transformer is protected at 125% of its full load
current. This is usually the case.
Fuses used on the primary side of transformers
must be capable of:
n Withstanding the magnetizing inrush to the
windings of approximately 12x the normal full load
current of the primary for 0.1 sec. without operation
or element damage.
n Carrying short-term overloads not exceeding
150% of the normal full load primary current.
The fuse ratings recommended meet these
requirements.

Motor Application
Standard motor starting duty is defined as motors having 6 x nominal FLA starting current, maximum 10 second
acceleration time and 4 evenly spaced starts per hour in a maximum 32 degree C ambient. If any of these
conditions are exceeded, use the Heavy duty column.
The motor data and fuse ratings presented are based on 1800 rpm high efficiency motors. For operating conditions or
motor types outside the scope of these tables, please request a copy of our Fusesoft v4.0 fuse selection software or
contact our offices with application details.
How to use motor tables

DAITO Alarm Indicating Fuses
Daito fuses are frequently used in machine tools, CNC and robotic equipment,
telecommunications and equipment from Fanuc, Yaskawa, Toshiba and
NEC.
They are AC/DC rated fuses with an integral alarm contact that is closed on
fuse operation, signalling that the fuse has operated.
They are a unique size and cannot be interchanged with other fuse types.
Other Daito designs as well as fuseholders available on request.

‘R’ Rated Motor Fuses
MVR fuses are current and energy limiting fuses intended for the backup
protection of medium voltage motor control. They are non-venting.
MVR fuses have integral striker/indicators and have standardized
dimensions compatible with today’s 5.5kV motor control gear. They are
fully interchangeable with other manufacturers’ fuses of the same type
and rating.
They feature a ‘field toughened’ element design which makes them less
susceptible to mechanical damage during shipping and installation while
also providing superior cycling characteristics.
Features
• Integral indicating pin
• Standard “R” Ratings
• Toughened element design
• Fully plated parts

Installation Notes:
R Rating Defined
1. When replacing ‘R’ fuses, always replace with the
same ‘R’ rating to maintain coordination and motor
starting capability.
2. These fuses can replace any manufacturers’ fuse of
same ‘R’ rating.
3. Ensure that fuse clips have good tension. (if you can
spin the fuse in the clips easily, clips should be
replaced.)
The ‘R’ rating of a fuse is established by dividing the
20-35s melt current of the fuse by 100.
Fuses of the same ‘R’ rating will have the same
time current characteristics and ensure identical
motor starting performance and coordination with
the overload relays.
4. Clean all contact surfaces before installation.
5. Install with striker pin facing up.
6. Unless the cause of fuse failure is known to have been confined to 1 phase, fuses should be replaced in sets
of 3 to ensure ‘As new’ performance.
Technical data presented.
Amp Rating
Each fuse has both an assigned ‘R’ and amp rating. It is the ‘R’ rating of the fuse that governs the motor
starting capability and coordination with the overload relays. To maintain the same capabilities, fuses
should be replaced with matching ‘R’ ratings.
9R
200A
On direct across the line starts, the necessity of passing the motor starting current results in a fuse selection with an
assigned amp rating well above the nominal motor full load amps.
However, applications using reduced voltage starts, variable frequency drives or other methods to reduce the motor
starting current, can result in a fuse rating with an amp rating too close to the motor F.L.A. As a check, the fuse’s assigned
full load amp rating should be a minimum of 140% of the nominal full load amps of the motor.

Read RMS fault value on lower scale and read up to where it intersects the line for the fuse
you are evaluating. From this intersection point, read across to the left hand scale to obtain
the peak current let-thru. Note: this value is in peak asymmetrical amperes. To convert to
RMS symmetrical, divide by 2.3. Peak let-thru graph is valid for all voltage classes.

Time current curves shown on pages 4-6 are minimum melting curves. For total clearing,
please refer to the curves on pages 7-9.
o
Characteristic curves are generated with the fuse at an ambient
temperature of 24-26 C. Ambient temperatures higher than 30 C may
require fuse de-rating. Please contact Fusetek in this instance.
Motor Application Tables.
Standard duty is defined as: 2 evenly spaced starts per hour, 25 C ambient temperature, 10 second run-up time
and a starting current of no more than 6X the nominal full load amp of the motor.
o
If any of these parameters are exceeded - use the heavy duty (HD) column.
•
Select the appropriate HP rating in the left column
•
Read across to the appropriate voltage and duty
column (Std or HD)
•
Use the ‘R’ rating of fuse specified
•
5.5kV fuses may be used on 2.3kV control.

E Rated Distribution fuses
E rated 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

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 nuisance blowing caused by element damage.

DIN HV Distribution
DIN HV fuses are partial-range high voltage current-limiting 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 a temperature sensitive striker to protect against extended overload conditions, or
external overheating.
Sealed for indoor or outdoor use.
Striker pin can be used for visual indication or mechanical actuation of other devices. (Std-80N, HD - 120N)
High amp ratings available for larger installations.
Fully plated parts for cool running.
Installation Notes
32
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 Fusetek 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.
Maximum voltages listed are absolute maximums for safe operation. Utility system tolerances on voltage
must be considered 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:
n Fuses must pass normal primary winding magnetising inrush currents: These are taken as 12x the normal full
n
n
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 27. Be sure to consider the switching options and proximity of other
banks when establishing a base FLC to apply. Fuses used on Capacitor fuses should be rated at 150% of system
voltage.

TFCF 600V Capacitor fuses
TFCF fuses are current limiting fuses designed for the unit fusing of 600v (or
less) capacitors. They are threaded for M12 metric capacitor bushings, but
may be adapted to other thread patterns with the adapters shown elsewhere
in this publication.
n
Metric threaded for direct screw on mounting to metric
capacitor studs.
Excellent short circuit performance.
Fully plated metal parts for cooler running.
n
n
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 Capacitor fuses
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.

KF22-12
HV Indicator
The KF22-12 is a solid state device that signals the presence of system
voltage by flashing an array of 3 high brightness red LED’s.
The KF22-12 works on the principle of capacitively coupling the device
through air to ground, so there is no high voltage wiring or clearance
issues.

British semiconductor fuses (BS88)
These fuses are British dimension, ultra fast acting types for the protection of
semiconductor devices such as diodes, rectifiers, SCR's, thyristors, etc.
They are used in electronic speed control devices such as soft-starts or
inverters, in power conversion equipment, or anywhere where sensitive electronic components need protection.
SIBA UR fuses have excellent energy let-thru characteristics under short
circuit conditions.

Eurofuses
European fuses are used in imported equipment, or in projects destined
overseas. Eurofuses are available in two broad categories - bottle fuses and
square body fuses. Both categories have many different types within the
group. See the individual tables. All European fuses are current and energy
limiting.

DIN 43 625 Ultrafast
Square body rectifier fuses are used in large drives and power
conversion equipment where larger amp ratings and superior short
circuit performance are required. SIBA UR fuses are fully compatible
with other manufacturers' fuses.

approved
DIN 43625 fuses come in 5 case sizes - 000, 00, 1, 2, & 3. Within these
case sizes - UR fuses come in two voltage ratings (700 & 1300Vac) and
two fixing centers (80 and 110mm). These fuses can easily be fitted with
a microswitch for remote annunciation, or may be used without this option.
DC de-rating factors
DC Application
URS series fuses can be used
on DC circuits with voltage levels
dictated by the time constant of the
circuit (l/r). Shorter time constants
are easier duty on the fuse and so
higher DC voltages can be tolerated. Usually, time constants are
20ms or less.
Refer to the chart at right to get the
equivalent working DC voltage once
the time constant is known.
