Bussmann LPN-RK-200 Class RK1 Fuse

Bussmann LPN-RK-200 Class RK1 fuse is a high-current, low-peak, time-delay, dual-element, current-limiting fuse in the Bussmann LPN-RK family, designed for use in CSA UL Class RK1 fuse blocks and holders. It is rated for 200 A at 250 V AC and delivers a high interrupting rating of 300 kA at 250 VAC and 100 kA at 125 V DC, providing robust protection in mains and motor-control circuits. As part of the RK1 lineup, it combines the Low-Peak design with the reliability of a dual-element fuse that tolerates momentary inrush without nuisance tripping, while still limiting fault currents to protect wiring and components. The LPN-RK series is built to meet standard RK1 performance, offering current-limiting protection for distribution panels, machine controllers, and other industrial electrical systems where fast fault clearing is required without compromising service during startup surges. Compatible with Bussmann RK1 fuse blocks and holders, this 200 A, 250 V-rated device is commonly used in industrial control panels, power distribution enclosures, and similar applications requiring consistent overcurrent protection with high interrupting capability. This fuse embodies Eaton’s Bussmann line, reflecting the integration of Bussmann protection technology into a broad portfolio of Class RK1 fuses for dependable, long-life circuit protection.
