Bussmann 225AMP600V Fuse

Bussmann FRS-R-225 fuse is a 225 A, 600 VAC current-limiting cartridge fuse in Eaton's Bussmann Series, designed for industrial power distribution and motor-control protection. With a DC rating of 300 VDC, it functions as a time-delay, dual-element device that helps limit fault currents while allowing temporary surges. It carries an interrupting rating up to 200 kA at 600 VAC and 20 kA at 300 VDC, making it suitable for high-energy circuits found in industrial controls, PV inverters, and large motor drives. This RK5-class, cartridge‑type fuse is non-indicating and intended for use with a compatible Bussmann fuse holder; its rugged construction supports harsh electrical environments and straightforward replacement in service panels and switchgear.
