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 1.5 1.0 Kp 0.8 UL K 1.6 1.4 1.2 103 1.0 2) 0.5 0.6 0.5 1) 0.4 2) 8 0.3 0.2 0.3 6 5 1) 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 0.15 316 Eg 460 604 Eg 3 300 700 1) 35-100 Amp Range 2) 125-600 Amp Range 3) 700-1200 Amp Range 400 500 600 Ib 0.1 30 40 50 700 60 70 80 90 100% 1) 125-600 Amp Range 2) 35-100 & 700-1200 Amp Range Dimensions Fig. 1: 5-800 Amp Range Fig. 2: 900-1000 Amp Range Fig. 3: 1200 Amp Range 3.500 1.375 J 0.125 0.500 5.966 7.594 A D E C 9.590 6.840 3.844 3.844 10.844 5.154 1.031 0.625 1.625 1.750 0.625 2.750 0.750 0.500 4.250 F 3.500 G H B Order # Fig. A B C D E F G H J FWP-5B-30B 1 2.870 0.563 1.855 2.477 2.477 0.250 0.405 0.063 0.250 FWP-35B-60B 1 4.375 0.813 2.750 3.708 3.312 0.344 0.725 0.125 0.542 FWP-70B-100B 1 4.406 0.947 2.594 3.625 3.563 0.344 0.750 0.125 0.375 FWP-125A-200A 1 5.090 1.500 2.840 4.190 3.500 0.410 1.000 0.250 0.750 FWP-225A-400A 1 5.090 2.000 2.840 4.280 3.530 0.410 1.500 0.250 0.780 FWP-450A-600A 1 7.090 2.500 2.840 5.720 4.190 0.530 2.000 0.380 1.300 FWP-700A-800A 1 6.630 2.000 2.844 5.562 5.062 0.625 1.500 0.250 0.875 FWP-900A-1000A 2 See Drawing FWP-1200A 3 See Drawing Dimension in inches. 1mm = 0.0394∑ 1∑ = 25.4mm The only controlled copy of this BIF document is the electronic read-only version located on the Bussmann Network Drive.
