Bussmann by Eaton FWH-250A Distribution Fuses

Bussmann by Eaton FWH-250A is a 250-amp high-speed fuse rated for up to 1000 VAC and 800 VDC. As a member of the Bussmann FWH high-speed family, it is a non-indicating, fast-acting overcurrent protection device designed to interrupt faults quickly. Its electrical ratings include a 200 kA interrupting rating at 1000 VAC and 50 kAIC at 500 VDC, enabling protection of large power paths and semiconductor power supplies. The FWH-250A is intended for use in industrial and commercial distribution networks that operate at high voltages, where fast disconnection minimizes damage to equipment and reduces downstream fault currents. With a 250 A RMS rating, it fits Bussmann’s standard high-current form factor for protection in switchgear, power distribution blocks, and DC bus applications. The FWH-250A protects power supplies, drives, and telecom infrastructure, providing precise, rapid fault clearance for demanding electrical systems.
