The Eaton Bussmann FWH-80 semiconductor fuse is a fast-acting high-speed fuse designed to protect power semiconductor devices by interrupting fault currents in high-voltage circuits. It is an 80 A, 500 V fuse in the FWH family, with a 24 mm by 44 mm body size that aligns with common 24x44 mm Bussmann footprints. Ideal for protecting power electronics such as inverters, motor drives, and IGBT modules, the FWH series is explicitly described for semiconductor protection and is rated for high-speed interruption in 500 V systems.
