High Speed Fuses Square body flush end contact -- 690V (IEC): 1000-4000A 690V (IEC) 1000-4000A 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%. Specifications Description: Square body flush end contact high speed fuses. Dimensions: See dimensions illustrations. Ratings: Volts: -- 690Vac Amps: -- 1000-4000A IR: -- 200kA RMS Sym. Power Losses 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). 1.5 1) K 1.0 0.5 0.4 UL 5 4 Eg 3 200 300 0.2 Eg 100 200 300 400 500 600 690 500 600 690 1.0 Kp 0.8 0.6 0.5 0.4 0.3 0.2 Ib 0.1 30 40 50 0.3 400 High Speed Fuses 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.
