Once a product has been selected, it should be tested by the user in all possible Style BS 88690V6-700A Total Clearing I2tThe total clearing I2t at rated voltage andat power factor of 15% are given in theelectrical characteristics.
4 For other volt-ages, the clearing I2t is found by multi-plying by correction factor, K , given as a function of applied working voltage,Eg, (RMS).Arc VoltageThis curve gives the peak arc voltage,UL, which may appear across the fuseduring its operation as a function of theapplied working voltage, Eg, (RMS) at apower 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, Kp,is given as a function of the RMS loadcurrent, Ib, in % of the rated current .Electrical )2)EgK15001000500200400600 660 EgUL1)2) 40 50607080 90 100% 2: ET, 1: CTFig.
