Cooper Bussmann LPS-RK-60SP RK1 Time-Delay Fuse

Cooper Bussmann LPS-RK-60SP is a Low-Peak, RK1-class dual-element time-delay fuse in the Bussmann LPS-RK family. This 60 A, non-indicating fuse is rated for 600 VAC or 300 VDC, with short-circuit interrupting ratings of 300 kA at 600 VAC and 100 kA at 300 VDC. The device uses ferrule-end terminals and a cylindrical body, with approximate dimensions of 1.06 in diameter by 5.5 in length. As a time-delay, current-limiting fuse, it tolerates brief inrush currents while protecting circuits in power-distribution panels and RK1 protection blocks that specify Bussmann LPS-RK fuses. The LPS-RK-60SP is designed to meet UL 248-12 requirements for Class RK1 fuses and is part of Eaton’s Bussmann series, providing reliable short-circuit protection with dual-element time-delay characteristics.
