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). 1.5 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%. 1.4 1.2 103 9 8 7 6 K 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. 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 . 0.2 4 0.2 Eg Eg 3 200 100 200 300 400 500 600 690 300 400 500 600 690 Ib 0.1 30 40 50 60 70 80 90 100% Dimensions DIN 43 620: Type DIN 000 Dimension in mm. 1mm = 0.0394∑ 1∑ = 25.4mm 54 Max Indicator 15 48 79 21 6 35 The only controlled copy of this BIF document is the electronic read-only version located on the Bussmann Network Drive.
