Description
The Bussmann LPJ-30SP is part of Eaton’s Low-Peak fuse range. This dual-element, time-delay Class J fuse provides current-limiting overcurrent protection for compatible industrial and commercial electrical circuits. Its time-delay characteristic helps reduce unnecessary fuse operation caused by temporary inrush currents.
