BUSSMANN FWP-250 Fuse

BUSSMANN FWP-250 is a high-speed semiconductor fuse from the Bussmann (Eaton Bussmann) family, rated at 250 A with both 700 VAC and 700 VDC operation. As a fast-acting cartridge fuse, it interrupts fault current quickly in power-electronic circuits, offering an interrupting capacity up to 200 kA at 700 VAC and up to 50 kA at 700 VDC. End-connection configurations vary by variant, including blade-end terminals on many versions and bolt-on body options on others. The model is commonly listed as FWP-250A in current catalogs and distributor pages, which confirms the 250 A rating and the 700 V rating for both AC and DC operation. This fuse is designed for protection in high-voltage semiconductor applications and power electronics where fast fault interruption is required.
