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%. 2.0 1.5 K 1.6 1.0 0.5 0.3 0.2 0.15 100 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 1.2 0.6 0.5 103 0.4 800 0.3 600 500 0.2 400 Eg 250 400 500 600 300 200 Eg 300 400 500 600 0.1 30 40 50 Ib 60 70 80 90 100% The only controlled copy of this BIF document is the electronic read-only version located on the Bussmann Network Drive.
