LPJ-100SP LOW PEAK FUSE

Product Description

The LPJ-100SP is an Eaton Bussmann Low-Peak® Class J dual-element, time-delay fuse designed for high-performance low-voltage branch circuit protection. It provides superior current-limiting capability and is widely used in industrial power distribution systems to protect motors, transformers, and control panels from short-circuit and overload conditions.

This fuse is engineered for high inrush current applications while still delivering fast fault clearing under short-circuit conditions, making it a reliable choice for selective coordination in complex electrical networks.
