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). 1.5 K 1.25 1.0 50-1400A (R) 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%. 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 0.6 0.5 0.4 3 2.5 1.8 1.4 UL 0.5 0.4 0.3 0.2 Eg 400 600 800 1000 1200 1400 103 8 6 5 4 3 400 600 800 Eg 1000 1200 1400 0.3 0.2 0.1 30 40 50 60 70 Ib 80 90 100% -----Dashed lines apply to the following amperages: Size Amp 1* 400 1 500-630 2 630-1000 3 800-1400 Dimensions DIN 43 653: Type -/110, -T/110 Size 1* 1 2 3 A 80 80 80 81 B 138 138 138 139 D 58 66 75 90 E 45 53 61 76 H 20 25 25 30 108 A Dimension in mm. 1mm = 0.0394 1 = 25.4mm H 11 D E B 6 E The only controlled copy of this BIF document is the electronic read-only version located on the Bussmann Network Drive.
