Bussmann LPJ-400SP

Bussmann LPJ-400SP

Overview

The Bussmann LPJ-400SP is a Class J dual-element time-delay fuse designed for heavy-duty industrial and commercial power systems. With a 400 A current rating and 600 V AC / 300 V DC voltage ratings, it provides exceptional overload and short-circuit protection. Its dual-element time-delay design allows it to withstand high inrush currents, making it ideal for motor and transformer circuits.

Built as a current-limiting fuse, the LPJ-400SP reduces fault energy during short-circuit conditions, protecting sensitive equipment and minimizing downtime. Its 300 kAIC interrupt rating at 600 V AC and 100 kAIC at 300 V DC ensure maximum circuit safety. Designed with a bolted blade end x bolted blade end connection, this fuse guarantees secure installation and long-term reliability.
