Bussmann by Eaton Lps-Rk-500Sp Time-Delay Fuse

The Bussmann by Eaton LPS-RK-500SP is a 500-amp time-delay fuse from the LPS-RK-SP Series, designed to protect heavy‑duty power circuits while tolerating brief inrush currents. Rated for 600 VAC and 300 VDC, it carries UL Class RK1 certification and is offered in a non-indicating cartridge style for clean panel installations. This bolt-on mount fuse measures 13-3/8 inches in overall length and 3-1/8 inches in diameter, making it suitable for large power‑distribution panels, industrial equipment, and motor‑control applications where high fault‑current protection is required without nuisance interruptions from short surges. The time-delay characteristic slows the fuse’s response to enable short-duration overloads to pass, while still interrupting sustained faults to safeguard wiring, components, and downstream devices. As part of Eaton’s Bussmann lineup, the LPS-RK-500SP adheres to standard RK1 performance requirements and is compatible with systems that specify 600 VAC, 300 VDC protection, and bolt-on fuse assemblies. In installations where space and amperage demand are extreme, this 500-amp, 600 VAC fuse provides a robust balance of surge tolerance and reliable fault interruption for demanding industrial power networks.
