Cooper Bussmann By Eaton LPN-RK-250 Class RK1 Fuse

Cooper Bussmann by Eaton LPN-RK-250 is a Low-Peak Class RK1 fuse engineered for high-current protection in 250-volt circuits. The device is a 250 A, 250 VAC dual-element, time-delay fuse that is current-limiting and offers an interrupting rating of 300 kA at 250 VAC. Available in both indicating (LPN-RK-250SPI) and non-indicating (LPN-RK-250SP) variants, it fits standard RK1 fuse holders and is part of Bussmann’s LPN-RK family. The Low-Peak geometry and RK1 compatibility support reliable protection in equipment where brief overloads and inrush currents occur, such as motor starters, transformers, and power-distribution panels. This Class RK1 fuse delivers controlled fault clearance while preserving circuit integrity, aligning with RK1 performance expectations for low-peak, time-delay fusing in 250 VAC systems. Use this fuse for 250 VAC control circuits and feeders that require current-limiting, time-delay protection with a robust interruption capability.
