The Bussmann FWH-700A is a high-speed semiconductor fuse from the Bussmann FWH family (Eaton), rated for 700 A RMS and 500 V (AC/DC) to protect power electronics circuits. Designed to interrupt fault currents quickly, it provides up to 200 kAIC at 1000 VAC and 50 kAIC at 500 VDC. This non-indicating cartridge fuse is offered with blade-end or stud terminations, making it suitable for high-current protection in power supplies, inverters, motor drives, and other semiconductor applications. As part of Eaton's Bussmann Electrical Division catalog, the FWH-700A serves as a rugged protection option for industrial power electronics requiring a 500 V rating and 700 A capacity.
