Littelfuse Bussmann LPJ-200SP Time Delay Fuse

LPJ-200SP is a Bussmann/Eaton Class J time-delay fuse rated at 200 A, built for inline bolt-on installation in industrial controls and power distribution equipment. The Low Peak, dual-element, current-limiting device carries a 600 V AC rating (300 V DC) and is designed to tolerate brief overloads while protecting circuits from sustained faults. With an interrupting rating of 300 kA at 600 VAC (and 100 kA at 300 VDC), it provides robust protection in high-short-circuit environments. The package measures about 41 x 146 mm and features a bolt-on body with TAB/BLADE terminals for secure mounting in switchgear, panels, or equipment racks. It is a non-indicating fuse, meaning it does not provide a visual status indicator. The LPJ-200SP is part of Bussmann’s LPJ time-delay family and is well suited for protecting large loads such as motors, transformers, and other industrial circuits that experience inrush or brief overloads but require fast restart after faults. Its dual-element construction helps limit damage and maintain system uptime in demanding applications, while the 200 A rating ensures compatibility with typical feeder protection schemes in 600 V distribution systems.
