Bussmann LPJ-1SP Dual Element Time-Delay Fuse

Bussmann LPJ-1SP is a Low Peak Class J dual-element time-delay fuse rated for 1 A with a maximum voltage rating of 600 VAC (300 VDC). The dual-element design provides separate overload and short-circuit protection, allowing the fuse to ride through startup surges common to power supplies and motor controls while delivering rapid interruption when a fault occurs. This UL Listed device (also listed by CSA and CE) is part of the LPJ Low Peak family and is used in control panels, power supplies, and other equipment where inrush currents must be tolerated without nuisance tripping. With its 1 A rating and 600 VAC/300 VDC ratings, the LPJ-1SP serves as a reliable protection option for circuits in industrial and commercial applications that require a time-delay response and dependable fault interruption, including protection of switched-mode power supplies, LED drivers, and general control circuitry.
