R ® 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 1.4 1.2 103 9 8 7 6 2) 1) 1.0 0.5 0.4 1.0 Kp 0.8 UL 0.6 0.5 0.4 0.3 5 0.3 Power Losses Watts loss at rated current is given in the electrical characteristics.
