The Bussmann LPN-RK-125SP is a Low Peak, Class RK1 fuse with current-limiting, time-delay protection in a cartridge-body design, suited for power panels, motor-control centers, and other RK1 applications. It is rated at 125 A and supports up to 250 VAC or 250 VDC, with an interrupting capacity listed as up to 300 kA at AC and 100 kA at DC. This time-delay, dual-element fuse provides protection while accommodating temporary surge currents, and it is non-indicating, meaning it lacks a built-in visual blown-state indicator. The LPN-RK-125SP is part of Bussmann’s LPN-RK-SP family and is documented in major catalogs and distributor pages as a 125 A, 250 VAC/VDC, time-delay, current-limiting cartridge fuse.
