Bussmann FWP-500 Semiconductor Fuse

FWP-500 is a Bussmann/Eaton high-speed semiconductor fuse rated for 500 A and 700 V, designed to protect power-electronic circuits from overcurrent transients. As part of the FWP series, it is a fast-acting cartridge fuse with a high interrupting capacity up to 20 kA, suitable for high-energy applications where robust protection for semiconductor power paths is needed. It is rated for 700 V in both AC and DC operation, enabling use in systems that run on either voltage type and helping prevent damage to rectifiers, inverters, and other high-current semiconductor devices. The FWP-500 is commonly stocked by major distributors under the Eaton Bussmann brand, reflecting its status as a standard protection device within the Bussmann semiconductor fuse family and its compatibility with other FWP-series parts in same-series configurations.
