8 / 21 page Ferrule — FWH 500V: 1-30A Dimensions - mm (inches) 50.8 (2.000") 15.5 (0.610") 14.3 (0.563") FWH (14 x 51mm) Specifications Description: Ferrule style high speed fuses. Dimensions: See dimensions illustration. Ratings: Volts: — 500Vac/dc Amps: — 1-30A IR: — 200kA RMS Sym. — 50kA @500Vdc Agency Information: CE, UL Recognition 1- 30A & CSA Component Acceptance: 5 - 30A. Electrical Characteristics Total Clearing I2t The total clearing I2t at rated voltage and at power factor of 15% are given in the elec- trical 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). 500 400 250 100 1.5 1.0 0.5 0.3 0.2 0.15 Eg K Arc Voltage 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%. 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, Kp, is given as a function of the RMS load current, Ib, in % of the rated current.
