Dimensions: See Dimensions illustrations. Ratings: Volts: — 150Vac Amps: — 70-1000A IR: — 100kA Sym. (70-400A) — 200kA Sym. (450-1000A) — 20kA @150Vdc (70-800A) — 100kA @ 80Vdc (70-400A) Agency Information: CE, UL Recognized Electrical Characteristics Total Clearing I2t The total clearing I2t at rated voltage and at power factor of 15% are given in the electri- cal characteristics. For other voltages, the clearing I2t is found by multiplying by cor- rection factor, K, given as a function of applied working voltage, Eg, (rms). Arc Voltage This curve gives the peak arc voltage, UL, which may appear across the fuse dur- ing its operation as a func- tion 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 correc- tion factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current.
