Worldwide Circuit Protection Solutions
Bussmann is a world-leading supplier of medium voltage
fuses. Each product is backed by an efficient worldwide
distribution network with unrivaled service and technical
support. Bussmann circuit protection solutions comply with
major international standards: ANSI, BS, DIN, IEC and UL.
Fuse Types
Medium voltage fuses generally fit into two categories –
expulsion fuses and current limiting fuses. The definitions per
ANSI C37.40 are:
Expulsion Fuse: “A vented fuse in which the expulsion effect
of the gases produced by internal arcing, either alone or
aided by other mechanisms results in current interruption.”
Expulsion fuses will limit the duration of an overcurrent
event, but they will not limit the magnitude of fault current.
Current Limiting Fuse: “A fuse unit that, when in its currentresponsive element is melted by a current within the fuse’s
specified current-limiting range, abruptly introduces a high
resistance to reduce current magnitude and duration,
resulting in subsequent current interruption.” A current
limiting fuse will reduce the magnitude a fault current as well
as limit the duration of the overcurrent event when operating
in its current limiting range. Bussmann offers a broad range
of current limiting fuses for protection of feeders,
transformers and motor circuits designed to ANSI, BS, DIN
and IEC standards.
Medium Voltage Current Limiting Fuses
Current limiting fuses are classified into three categories:
1. Full Range – defined by ANSI C37.40 as “a fuse capable
of interrupting all currents from the maximum rated
interrupting current down to the minimum continuous current
that causes the melting of the fusible element(s), when the
fuse is applied at the maximum ambient temperature
specified by the manufacturer.” It is able to interrupt any
current that will melt its element.
within this range. It is possible for the fuse to be exposed to
an overcurrent lower than the value given by the one hour
criteria. In that case, a different overcurrent protection device
would be required to interrupt the overcurrent.
3. Back-up – defined by ANSI C37.40 as “a fuse capable of
interrupting all currents from the maximum interrupting rating
current down to the minimum interrupting current.”
The minimum interrupting current is the lowest current that
the fuse will be able to clear properly. This creates a need to
place a low current interrupting device, such as motor
overloads, in series with the back-up rated fuse.
E- and R-Rated Fuses
In North America, current limiting fuses typically fall into the
category of E-Rated fuses and R-Rated fuses. Bussmann
also offers a wide range of current limiting fuses designed to
BS, DIN and IEC standards.
E-Rated fuses are used to protect feeder circuits, power
transformers and potential transformers. E-Rated fuses have
defined current response times specified by ANSI C37.46.
E-Rated fuses 100A and below must melt in 300sec at an
rms current within the range of 200% to 240% of the
continuous current rating. E-Rated fuses above 100A must
melt in 600sec at an rms current within the range of 240% to
264% of the continuous current rating of the fuse.
Bussmann offers a wide variety of full range and general
purpose E-Rated fuses from 2.4kV up to 38kV.
R-Rated fuses are back-up fuses that provide short-circuit
protection for motor circuits. They are applied with MV motor
starters which provide the overload protection for the circuit.
R-Rated fuses also have defined current response times
specified by ANSI C37.46. R-Rated fuses will melt in a range
of 15 – 35sec at a current equal to 100 times the “R” rating.
Bussmann offers 2.4kV, 5.08kV, 7.2kV and 8.3kV R-Rated
fuses for motor circuit protection.
2. General Purpose – defined by ANSI C37.40 as “a fuse
capable of interrupting all currents from the maximum rated
interrupting current down to the current that causes melting
of the fusible element(s) in one hour.” Not all currents fall

Fuses
Features and Benefits
• Clip-lock and bolt-in style available in double and triple
barrel fuse designs for application flexibility
• The filament wound, glass epoxy fuse tube provides
moisture protection for the fuse. This makes Cooper
Bussmann medium voltage fuses suitable for both indoor
and outdoor application (outdoor applications require
installation inside an appropriate enclosure)
• Open fuse indication (indicator travel distance is 16mm)
easily integrates into automation schemes
• 50/60Hz operating frequency make these fuses applicable

Medium Voltage Fuses
British Standard Dimensioned IEC Fuses for
Motor Circuit Protection
The Bussmann range of motor fuses are designed to meet
the specific requirements necessary for motor protection.
During the starting cycle of direct on-line motors, the fuse
elements will reach a considerably higher temperature than
during normal operation; (this is due to the high amount of
current the motor will draw as it starts, typically, six times its
normal load current value). This results in expansion and
contraction of the fuse elements and could cause premature
operation of the fuse.
Bussmann motor fuses encompass an advanced design to
minimize this effect. This therefore, negates the need to over
specify the fuse rating due to high values of motor starting
current.
Bussmann motor fuses operate extremely quickly under
heavy fault currents, resulting from the time / current
characteristic. Low power dissipation ensures low
temperature rise, important in multi-tier starters for example.
Switching (arc), voltages are lower than permitted values,
therefore, 5.5kV fuses are also suitable for 4.8kV and
2.4kV circuits.

• Wide range of options available from 15kV to 72kV in ANSI
T & K characteristics.
• Extra rapid option also available.

Up to and including 50A: 25 in a carton
From 60A to 100A: 10 in a carton
To avoid incorrect replacement the fuse links have colour
coded labels:
Pink label: Type XA
Yellow label: Type K
Green label: Type T
Typical Applications:
• Primary side transformer protection
• Feeder protection
• Capacitor bank protection
Use of Application
Expulsion fuse links current ratings should be selected on the
basis of maximum expected transient no damage currents
rather than on full load current. In addition, the selection of
higher current ratings will reduce the possibility of supply
interruption due to transient surges such as those due to
lightning strikes.
Links should be handled with a reasonable degree of care
when installing. Excessively rough handling may damage the
element.
It is normal, under certain fault conditions, for arc
extinguishing material and/or metal particles to be expelled
from the fuse assembly. It is therefore recommended that
reasonable precautions be taken to prevent the installation
being approached by unauthorised persons.

Typical Applications
• Medium Voltage Fused Cutouts
High-surge, Type H fuses are manufactured in ratings of 1, 2,
3, 5, and 8A. They have been developed principally for
primary fusing of small-sized transformers. Type H links are
manufactured in the universal buttonhead design.
Type N Fuses
Type N fuses conform to previous NEMA standards and have
been superseded by Type K and T links. Type N fuses are
manufactured in the universal button design in ratings of 5
through 200A for use in NEMA standard dimensioned cutouts
rated through 27kV.
