Eaton Bussmann LPSRK100SP Current-Limiting Fuse

The Bussmann by Eaton LPS-RK-100SP is a 600VAC/300VDC, 100A dual element, time-delay fuse designed for comprehensive circuit protection. It features Class RK1 current-limiting technology, is UL-listed and CSA-certified, with a 300kA voltage interrupting rating suitable for a wide range of industrial applications. Its time-delay characteristic, with a minimum of 10 seconds at 500% of rated current, allows for high inrush currents in motor and transformer circuits. The fuse provides effective short-circuit protection, reduces arc flash hazards, and offers easy selective coordination with other low-peak fuses using a simple 2:1 ampacity ratio. It is suitable for feeders, branch circuits, motors, transformers, solenoids, and general-purpose circuits. Additional safety features include electrically isolated end caps and low watt loss power consumption.
