Arc VoltageThis curve gives the peak arc voltage,U , which may appear across the fuseL

during its operation as a function of theapplied working voltage E, (RMS) at ag

power factor of 15%.

Power LossesWatts loss at rated current is given inthe electrical characteristics. The curveallows the calculation of the powerlosses at load currents lower than therated current. The correction factor, K ,p

is given as a function of the RMS loadcurrent, I , in % of the rated current.b

Arc VoltageThis curve gives the peak arc voltage,U , which may appear across the fuseL

during its operation as a function of theapplied working voltage E , (RMS) at ag

power factor of 15%.

Power LossesWatts loss at rated current is given inthe electrical characteristics. The curveallows the calculation of the powerlosses at load currents lower than therated current. The correction factor, K ,p

is given as a function of the RMS loadcurrent, I , in % of the rated current.b

Dimensions

Dimensions in mm1mm = 0,0394" 1" = 25,4mm

2Total clearing I t2The total clearing I t at rated voltage and

at power factor of 15% are given in theelectrical characteristics. For other volta-

2ges, the clearing I t is found by multi-plying by correction factor, K, given asa function of applied working voltage,E , (RMS).g
