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 correc- tion factor, k p , is given as a function of the rms load current, i b , in % of the rated current. features and benefits ? excellent dc performance ? low arc voltage and low energy let-through (i 2 t) ? low watts loss ? superior cycling capability typical applications ? dc common bus ? dc drives ? power converters/rectifiers ? reduced voltage starters for product data sheets, visit www .cooperbussmann.com/products/datasheet.asp 128 square body din 43 653 1250v/1300v (iec/ul): 50-1400a high speed fuses 1250v/1300v (iec/ul) 50-1400a specifications description: square body din 43 653 stud-mount high speed fuses. dimensions: see dimensions illustration. ratings: volts: 1250vac (iec) 1300vac (ul) amps: 50-1400a ir: 100ka rms sym. agency information: ce, designed and tested to iec 60269: part 4, ul recognized. consult cooper bussmann for ul recognition/csa component acceptance status. electrical characteristics total clearing i 2 t the total clearing i 2 t at rated voltage and at power factor of 15% are given in the electrical characteristics. for other voltages, the clearing i 2 t is found by multiplying by correction factor, k, given as a function of applied working voltage, e g , (rms). u l 3 2.5 8 10 3 1.4 1.8 6 4 5 3 400 600 800 1000 1200 1400 e g dashed lines (- - - - - -) apply to the following amperages:. size amps. 1* 400a 1 500-630a 2 630-1000a 3 800-1400a k 1.5 1.0 1.25 0.5 0.4 0.3 0.2 400 600 800 1000 1200 1400 e g k p 30 40 50 60 70 80 90 100% i b 1.0 0.8 0.4 0.5 0.6 0.3 0.2 0.1 a b 108 d e e 6 h 11 dimensions (mm) type -/110, -tn/110 size a b d** e h 1* 80 138 58 45 20 1 80 138 66 53 25 2 80 138 75 61 25 3 81 139 90 76 30 **microswitch. 1mm = 0.0394 / 1 = 25.4mm
