General pplications Rated Voltage The C voltage rating of ussmann fuses is given in volts rms. tested to IEC are tested at 5% above their rated voltage. ritish Style S 88 fuses are tested at 10% above its rated voltage. UL recognition tests are performed at the rated voltage. Rated Current Rated current is given in amps rms. ussmann fuses can continuously carry the rated current. Power Factor 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. X 0.9 0.8 Melting Characteristic The melting characteristic shows the virtual melting time in seconds as a function of the prospective current in amps rms. The fuses are specially constructed for short-circuit protection against high level fault currents. Loading and operation of the fuse in the noncontinuous/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. Virtual Pre-rcing Time In Seconds 10 10 10 Clearing Integrals The total clearing I t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I t is found by multiplying by correction factor, K, given as a function of applied working voltage, E g, (rms). 10 8 10 8 1.5 0. 0.

Power Losses Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, K p, is given as a function of the RMS load current, I b, in % of the rated current. 10 5 10 10 10 0.7 0.1 0. 0. COS 1. 1.

When a fuse operates in its current-limiting range, it will clear a shortcircuit in less than 1 cycle. lso, it will limit the instantaneous peak let-through current to a value substantially less than 1
General pplications that obtainable in the same circuit if that fuse were replaced with a solid conductor of equal impedance. asymmetrical current symmetrical current Parallel Connection When fuses are connected in parallel it is recommended that the applied voltage does not exceed 0.9 U N (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. nd it must be checked, that the maximum load current is not exceeded. Series Connection 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 U N (the rated voltage of the fuse). Mounting Guidance The recommendations below have to be followed when mounting a ussmann fuse with end plate threaded holes. 1. Screw in studs: 5 N m Max, 3 N m Min. ttachment of the fuse to bussbar by means of nut and washer: Thread Torque (N m)* Configuration Max Min 5 1 18, M8 5 0 3 8 1, M10 5 0 3 8 5 0 1 13, M1 5 50 1 0 5 50 *1 N m = 0.7375 lb-ft Overloads The design of ussmann 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. Overloads less than one second termed impulse loads. The following table gives general application guidelines which, in the expression Imax < (% factor) x I t. I t 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 I max. Frequency of Occurrence Overloads (> 1 sec) Impulse Loads (< 1 sec) Less than once per month I max < 80% x I t I max < 70% x I t Less than twice per week I max < 70% x I t I max < 0% x I t Several times per day I max < 0% x I t 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 ussmann 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. ny 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 ussmann for Reduction Factor additional information and application assistance when fuses have to operate under DC conditions. 0.9 Load Current Versus Conductor Cross Section 0.8 0. 0.7 0.8 0.9 (IEC cross section) Reduction of permissible load current when the conductor cross section is less than that given in IEC Publication 9-1 & valid for ussmann high speed fuses. pplication ssistance If you have application problems or need a fuse outside our standard program, please contact the nearest ussmann representative.

North merican Fuse ccessories Fuse ases (locks) Modular Style ussmann offers a comprehensive line of fuse bases that provide the user with design and manufacturing flexibility. Two identical half bases make up a ussmann modular fuse base. These split units can be panel mounted any distance apart to accommodate any length fuse. Stud Type (Not sold in pairs) The simpler design is the C58 Series modular fuse base. With this design, the fuse terminal and cable (with termination) are mounted on the same stud, minimizing labor needed for installation.
