Sizing class j fuses
WebbSelectivity is determined from the let through energy I 2 t characteristics.. The selectivity limit current is the value at which the total operating I 2 t of the downstream fuse exceeds the pre-arcing I 2 t of the upstream fuse.. In the short-circuit zone the let through energy of a fuse is constant and therefore the comparison may be made from the tabulated … Webbthe tables provided, the closest fuse rating that exceeds the drive rating should be chosen. • IEC – BS88 (British Standard) Parts 1 & 2 (1), EN60269-1, Parts 1 & 2, type gG or equivalent should be used. • UL – UL Class CC, T, RK1 or J must be used.
