Eaton Bussmann LPJ-200SP Low-Peak Fuse, 200A 600V AC, Class J Dual-Element Time-Delay - Pack of 3

Low-Peak™ LPJ Series Class J Dual-Element Time-Delay Fuse - Eaton Bussmann Series

The Eaton Bussmann LPJ-200SP is an industry-standard Class J current-limiting fuse, engineered to deliver superior protection for critical electrical circuits. As part of the Low-Peak™ series, this dual-element fuse provides a minimum 10-second time-delay at 500% of its rated current. This allows the fuse to handle temporary power surges and motor starting currents without nuisance tripping, ensuring higher system uptime in demanding industrial environments.

With an extremely high interrupting rating of 300kA at 600Vac, the LPJ-200SP offers heavy-duty protection against the most severe fault currents. Its current-limiting design significantly reduces the peak let-through energy and magnetic forces that can damage downstream components. The compact Class J physical dimensions enable designers to utilize smaller disconnects and enclosures, effectively reducing the overall footprint of electrical assemblies.
