Bussmann LPS 500 Time Delay Fuse Low Peak Dual Element 500A 600V

The Bussmann LPS-RK-500SP Low Peak dual-element time-delay fuse (Class RK1) is a 500 A protection device rated for 600 VAC and 300 VDC, designed for branch circuits and power-distribution panels in 600 V systems. Its dual-element, time-delay design tolerates short-duration overloads while delivering current-limiting protection during longer faults, reducing nuisance trips in motor and processing circuits. With blade-end terminals, the fuse carries an interrupting rating of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC, making it suitable for demanding industrial applications such as motor-control centers, feeders, and control circuits where reliable overcurrent protection is required. As part of the Eaton Bussmann Series, the LPS-RK family emphasizes Low Peak performance to minimize arc energy and improve safety in compact installations, while meeting UL RK1 600 V class standards.
