Watts loss provided at rated current. 130 Vdc U.L. Recognition on 1000 through 2000 amperes only. See accessories on page 20. 1 kg = 2.2 lbs 1 lb = 0.45 kg 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, E g , (RMS). Arc Voltage This curve gives the peak arc voltage, U L , which may appear across the fuse during its operation as a function of the applied working voltage, E g , (RMS) at a power factor of 15%. 1.5 K 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, K p , is given as a function of the RMS load current, Ib , in % of the rated current . 1.0 Kp 0.8 UL 1.0 0.6 0.5 300 0.4 0.5 0.2 0.3 0.2 0.15 26 12-28-98 SB98107 0.3 200 100 Eg Eg 65 Rev.
