Eaton Bussmann LPJ-600SP Low-Peak Fuse, 600A 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-600SP is a high-capacity Class J dual-element fuse from the renowned Low-Peak™ series. It provides the ultimate circuit protection by combining fast short-circuit response with a minimum 10-second time-delay at 500% of the rated current. This dual-element design allows the fuse to handle harmless temporary overloads and motor starting surges without nuisance tripping, while its current-limiting characteristics provide superior protection against damaging thermal and magnetic effects of short-circuit currents.

Engineered for reliability, the LPJ-600SP features a high interrupting rating of 300kA at 600Vac, making it suitable for a wide variety of industrial power distribution and motor control applications. Its compact Class J footprint allows for significant equipment downsizing compared to other fuse classes.
