| High Speed Fuses North American FWA 150V 70-1000A Specifications Description North American style stud-mount fuses. Dimensions See Dimensions illustrations. Ratings Volts 150Vac/dc* Amps 70-1000A IR 100kA Sym. 70-400A 200kA Sym. 450-1000A 20kA 70-800A 100kA 80Vdc 70-1000A *1000A rated 80Vdc. Agency Information CE, UL Recognized JFHR2.E91958 Electrical Characteristics Total Clearing I2t The total clearing I2t 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 . 70 102 1 500-1000A Range 2 70-400A Range Dimensions - in Fig. 1 70-400A Fig. 2 500-1000A Arc Voltage This curve gives the peak arc voltage, UL, which may 300 appear across the fuse during its operation as a function of the applied working voltage, Eg, rms at a power factor of 100 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. 30 40 50 60 Catalog Numbers Electrical Characteristics Rated I2t A2 Sec Catalog Current Clearing Number RMS-Amps Pre-arc at 150V FWA-70B |
