Bussmann By Littelfuse LPJ-250SP Low-Peak Fuse

LPJ-250SP is a 250 A Low-Peak Class J fuse from the Bussmann LPJ family, a dual-element, time-delay (current-limiting) protector designed for electrical distribution and industrial power circuits. It is rated for 600 VAC and 300 VDC, with an interrupting rating of 300 kA at 600 VAC and 100 kA at 300 VDC, providing robust short-circuit protection while tolerating brief inrush conditions. The unit is configured in a bolt-on body style for secure panel mounting, and open fuse indication is available across LPJ part numbers. Typical applications include protection of feeders, motor control centers, power supplies, and other industrial equipment in electrical distribution panels, where reliable protection with fast clearance and predictable coordination is essential. The LPJ series emphasizes safety and performance in high-energy systems, combining the Low-Peak profile with dual-element time-delay characteristics to minimize nuisance openings and improve selectivity in both AC and DC circuits.
