General Applications Rated Voltage
Power Factor
The AC voltage rating of Cooper Bussmann® fuses is given in volts rms. Fuses tested to IEC are tested at 5% above their rated voltage. British Style BS 88 fuses are tested at 10% 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.

High Speed Fuses
General Applications with a solid conductor of equal impedance. A asymmetrical current B symmetrical current Parallel Connection 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.
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). 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 bussbar by means of nut and washer: Thread Configuration 5 ⁄16” – 18, M8 3 ⁄8” – 16, M10 3 ⁄8” – 24 1 ⁄2” – 13, M12 1 ⁄2” – 20 *1 N•m = 0.7375 lb-ft
Torque (N•m)* Max Min 25 20 45 40 45 40 65 50 65 50
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
Frequency of Occurrence Less than once per month Less than twice per week
Overloads (> 1 sec) Imax < 80% x It Imax < 70% x It
Impulse Loads (< 1 sec) Imax < 70% x It Imax < 60% x It
Several times per day
Imax < 60% x It
—
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 shortcircuit 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.
