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. Features and Benefits • Excellent DC performance • Low arc voltage and low energy let-through (I2t) • Low watts loss • Superior cycling capability Typical Applications • DC common bus • DC drives • Power converters/rectifiers • Reduced voltage starters Square Body US Style — 690V/700V (IEC): 40-2000A 690V/700V (IEC) 40-2000A Specifications D De es sc crriip pttiio on n:: Square body US style high speed fuses. D Diim me en ns siio on ns s:: See dimensions illustration. R Ra attiin ng gs s:: Volts: — 690Vac (IEC) — 700Vac (UL) Amps: — 40-200A IR: — 200kA RMS Sym. A Ag ge en nc cy y IIn nffo orrm ma attiio on n:: CE, Designed and tested to IEC 60269: Part 4, UL Recognized. Consult Cooper Bussmann for UL Recognition/ CSA Component Acceptance status. 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).
