High Speed Fuses Ferrule — FWC 600V: 6-32A FWC (10 x 38mm) Specifications Description: Ferrule style high speed fuses. Dimensions: See dimensions illustration. Ratings: Volts: — 600Vac/dc Amps: — 6-32A IR: — 200kA RMS Sym. — 50kA @ 700Vdc (6-25A) Agency Information: CE, UL Recognition: 6-32A. UL Recognition: 6-25A 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 I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (rms).

The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current. 1.5 2 This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as a function of the applied working voltage, Eg, (rms) at a power factor of 15%.
