The LPJ-300SP is a 2-element time-delay Power Fuse provides ultimate protection. The ultimate protection LPJ class-J current-limiting time-delay fuse reduces existing fuse inventory by up to 33% when upgrading to low-peak fuse. The consistent 2:1 ampacity ratios for low-peak fuse make selective coordination easy. Current-limitation protects downstream components against damaging thermal and magnetic effects of short-circuit currents. It can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail. Long time-delay minimizes needless fuse openings due to temporary overloads and transient surges.
