Rated Voltage
The ac voltage rating of Cooper Bussmann® fuses is given in
volts rms. Fuses tested to IEC are tested at 10% above their
rated voltage. British Style BS 88 fuses are tested at 5%
above its rated voltage. UL recognition tests are performed at
the rated voltage.
For other power factor
values, the total clearing
integral can be calculated as a multiple of the
clearing integrals, the
correction factor K and
the correction factor X.

A fuse operation relating to short-circuits only. When a fuse
operates in its current-limiting range, it will clear a short-circuit in less than 1⁄2 cycle. Also, it will limit the instantaneous
peak let-through current to a value substantially less than
that obtainable in the same circuit if that fuse were replaced
with a solid conductor of equal impedance.

Virtual Pre-Arcing Time In Seconds
The melting characteristic shows
the virtual melting

a function of the
prospective current
in amperes rms.
The fuses are specially constructed
for short-circuit protection against high
level fault currents.
Loading and operation of the fuse in
the non-continuous/dashed section
of the melt curve
must be avoided.
The curve can also
be read as the real
melting time as a
function of the
RMS value of the
pre-arc current.

High Speed Fuses
General applications
Parallel Connection
Frequency of Occurrence
Less than once per month
When fuses are connected in parallel it is recommended that
the applied voltage does not exceed 0.9 UN (the rated voltage of the fuse). This is due to the fact that the energy
released within the fuses may be unevenly shared between
the parallel connected barrels.
When fuses are connected in parallel, one must take into
account that the current sharing is not necessarily equal.
And it must be checked, that the maximum load current is
not exceeded.
Series Connection
Mounting Guidance
The recommendations below have to be followed when
mounting a Cooper Bussmann fuse with end plate threaded
holes.
1. Screw in studs: 5 N•m Max, 3 N•m Min
2. Attachment of the fuse to buss-bar by means of nut and
washer:

Impulse Loads (< 1 sec)

—
When impulse loads are an intrinsic/normal parameter of the
load current either as single pulse or in trains of pulses or
when their level is higher than the melting current at 0.01
seconds (per time-current curve), contact Cooper Bussmann
for application assistance.
In addition to the parameters set forth in the preceding table,
the RMS value of the load current as calculated for any
period of 10 minutes or more should not exceed the maximum permissible load current.
Furthermore, it is important that a fuse should not be applied
in the non-continuous/dashed portion of the associated
time-current curve.
Any time-current combination point which falls in the
non-continuous/dashed portion of the time-current curve is
beyond the capability of the fuse to operate properly.
DC Operation
Depending upon the short-circuit time constant and the magnitude of the prospective short-circuit current, the dc voltage
at which a fuse can be applied may be less than its ac rating.
Long time constants require a lower dc voltage. Conversely,
however, higher available prospective short-circuit currents
result in faster fuse openings and thus permit a fuse to be
operated at a higher dc voltage.
Consult Cooper Bussmann for additional information and
application assistance when fuses have to operate under dc
conditions.
Overloads
The design of Cooper Bussmann® fuses is such that they
can be operated under rather severe operating conditions
imposed by overloads (any load current in excess of the
maximum permissible load current).
In applications, there will be a maximum overload current,
Imax, which can be imposed on the fuse with a
corresponding duration and frequency of occurrence.
Time durations fall into two categories:
1. Overloads longer than one second
2. Overloads less than one second termed “impulse” loads.
The following table gives general application guidelines
which, in the expression Imax < (% factor) x It. It is the melting current corresponding to the time “t” of the overload duration as read from the time-current curve of the fuse. The
guidelines in the table below determine the acceptability of
the selected fuses for a given Imax.

High Speed
Fuses
Fuses in series may not equally divide the applied voltage. It
is recommended that series connected fuses should only be
operated at fault currents that yield melting times less than
10 ms and a recovery voltage per fuse of less than or equal
to 0.9 UN (the rated voltage of the fuse).

Cooper Bussmann offers a complete range of North
American blade and flush-end style fuses and accessories.
Their design and construction were optimized to provide:
• Low energy let-through (I2t)
• Low watts loss
• Superior cycling capability
• Low arc voltage
• Excellent dc performance
North American style fuses provide an excellent solution for
medium power applications. While there are currently no
published standards for these fuses, the industry has
standardized on mounting centers that accept
Cooper Bussmann fuses.
Voltage Rating
All Cooper Bussmann® North American style fuses are tested
at their rated voltage. Cooper Bussmann should be consulted
for applications exceeding those values.
Accessories
External and internal open fuse indication is available for
selected portions of the North American line. Fuse blocks are
available for most applications.

The Cooper Bussmann Paul P. Gubany Center in St.
Louis is certified by Britain’s prestigious ASTA
(Associated Short Circuit Testing Authority) to
perform short testing of its own devices designed to
operate to ASTA requirements which are closely tied
to IEC requirements. The Gubany Center is the only
testing facility available in North or South America
for this product certification.

The Gubany Center has equipment capable of
generating 300,000A of current at 600Vac threephase, and 100,000A at 170Vdc, under carefully
controlled conditions. It offers a wider range of
current voltage and frequency configurations than
any other facility of its kind in the world, and is built
to exceed the short circuit capacity of today’s high
power electrical distribution systems.

Cooper Bussmann has been named as the vendor
offering the highest value in electrical fuses in a
recent fill-in-the-blank survey of nearly 40,000
qualified readers of Plant Services Magazine. A full
70 percent of survey respondents said Cooper
Bussmann was their number one choice. The
nearest competitor weighed in at only 7 percent. The
63 percent spread was the widest of all 63 product
categories, ranging from aerial work platforms to
welding equipment. According to Plant Services
editors, the products chosen are those “that deliver
the combination of functionality, durability and low
maintenance that add up to the lowest estimated
life-cycle cost”—those offering the very best value in
their product category.
