Ratings: Volts: -- 500Vac Amps: -- 35-1600A IR: -- 200kA Sym. -- 50kA @ 500Vdc Agency Information: CE, UL Recognition & CSA Component Acceptance on 35-800A only (50kA IR@500Vdc). UL Recognition on 35-1200A only, CSA Component Acceptance: 35-1600A. This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as a function of the applied working voltage, Eg, (rms) at a power factor of 15%. 1.6 1.5 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, Eg, (rms). 1.0 Fig. 1 1 1 1 1 1 1 2 C 1.593 1.736 1.836 2.090 2.090 2.090 3.219 1) 0.3 0.2 2) Eg 0.15 100 250 400 500 D 2.541 2.853 2.892 3.440 3.530 4.970 5.465 E 2.193 2.807 2.768 2.750 2.780 3.440 4.475 F 0.344 0.352 0.344 0.410 0.410 0.530 0.625 G 0.719 0.750 1.000 1.000 1.500 2.000 2.375 H 0.125 0.125 0.188 0.250 0.250 0.380 0.438 1mm = 0.0394" / 1" = 25.4mm Fig. 1: 35-1200A A D E C H G F B J Fig. 2: 1400-1600A 10.219 0.125 0.5 3.219 1) 400 Eg 200 300 400 500 1) 35-200 & 1000-1600A Range 2) 225-800A Range 1.0 Kp 0.8 0.6 0.5 0.4 0.3 0.2 Ib 0.1 30 40 50 J 0.518 0.375 0.406 0.750 0.780 1.300 1.120 Catalog Numbers FWH-35B FWH-40B FWH-45B FWH-50B FWH-60B FWH-70B FWH-80B FWH-90B FWH-100B FWH-125B FWH-150B FWH-175B FWH-200B FWH-225A FWH-250A FWH-275A FWH-300A FWH-325A FWH-350A FWH-400A FWH-450A FWH-500A FWH-600A FWH-700A FWH-800A FWH-1000A FWH-1200A FWH-1400A FWH-1600A Rated Current RMS-Amps 35 40 45 50 60 70 80 90 100 125 150 175 200 225 250 275 300 325 350 400 450 500 600 700 800 1000 1200 1400 1600 60 Electrical Characteristics I2t (A2 Sec) Clearing Pre-arc at 500V 34 150 76 320 105 450 135 670 210 900 210 900 305 1400 360 1600 475 2000 800 3500 1100 4600 1450 6200 1900 8500 4600 23300 6300 32200 7900 40300 9800 49800 13700 63800 14500 72900 19200 96700 24700 127000 29200 149000 41300 206000 55000 298000 76200 409000 92000 450000 122000 600000 200000 1000000 290000 1400000 * Watts loss provided at rated current. 70 80 90 100% 3.5 0.75 4.25 Watts Loss 8 7.5 7.5 7.5 9.9 10.6 12.7 15 17 25 30 35 40 39 41 46 51 53 58 65 74 84 108 120 129 145 180 210 230 * See accessories on page 106. 0.625 1.625 1.750 6.219 8.969 600 2) 500 Catalog Numbers 0.5 1) 35-800A Range 2) 1000-1600A Range A B 3.188 0.813 3.625 0.947 3.625 1.156 4.340 1.500 4.340 2.000 6.340 2.500 6.969 3.000 See Drawing 800 300 100 Watts loss at rated current is given in the electrical characteristics.
