Bussmann LPJ-30SP Time Delay Fuse

LPJ-30SP is a Bussmann Series Class J low-peak, dual-element time-delay fuse rated at 30 A, designed to tolerate inrush currents while protecting circuits. It features a cylindrical body with a yellow label and is specified for 600 V AC and 300 V DC operation, offering an interruption rating up to 300 kA at 600 VAC and 100 kA at 300 VDC. As a time-delay, current-limiting device, it uses separate overload and short-circuit elements to provide reliable protection for loads with brief surges and high inrush currents, such as motors and other power-supply or transformer-related applications, while remaining non-indicating in the field. The LPJ-30SP is intended for use with Class J fuse holders in control panels and electrical distribution, and it belongs to Eaton’s Bussmann Low-Peak family, delivering protection tailored to high-inrush environments.
