Bussmann LPS-RK-300 Low Peak Dual Element Fuse

The Bussmann LPS-RK-300 Low Peak Dual Element Fuse is a 300 A, 600 VAC/300 VDC cartridge fuse designed for RK1-class protection in general power circuits. As a Low Peak, dual-element time-delay device, it provides reliable short-circuit protection while tolerating inrush currents common to motors and transformers. The fuse is rated for 600 VAC and 300 VDC operation, with an interrupting rating of 300 kA at 600 VAC and 100 kA at 300 VDC, ensuring robust fault interruption in demanding electrical systems. Available in non-indicating LPS-RK-300SP and indicating LPS-RK-300SPI variants, both share a cartridge-body construction designed for RK1 fuse blocks and are compatible with Bussmann RK1 protection schemes; typical configurations fit fuse blocks such as HM600 and RM600. Applications include general-purpose protection in industrial control panels, power distribution equipment, and machinery where moderate-to-high current protection is required and inrush currents are anticipated.
