Rated Current RMS-Amps Size ® BIF # 17056314 1 kg = 2.2 lbs. 1 lb = 0.45 kg Rated Current The rated current of this fuse range has been given with copper conductors that have a current density of 1.3 A/mm2 (IEC 60269-4). For conductor cross section according to IEC 60269-1, the fuses must be derated.

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 3 100 200 300 400 500 600 690 200 300 400 500 600 690 Ib 0.1 30 40 50 60 70 80 90 100% Dimensions DIN 43 620: Type DIN 1*, DIN 2, DIN 3 Size A 1* 2 3 69 69 68 B D 135 58 150 71 150 88 E F H 45 55 76 40 48 60 20 26 33 Dimension in mm. 1mm = 0.0394∑ 1∑ = 25.4mm A Indicator H D F B E 6 This bulletin is intended to clearly present comprehensive product data and provide technical information that will help the end user with design applications.
