The XL50F800A is an 800 A, high-speed semiconductor fuse from Eaton Bussmann’s XL50F family, engineered to protect power‑electronics circuits by rapidly interrupting fault currents. It is rated for 500 V (AC/DC) and features a round body with center terminals for easy installation, with catalogs listing it as FWH-800A. This S/COND (1) fuse protects semiconductor devices in demanding 500 V power‑electronic systems, delivering fast response in fault conditions. As a UL‑class semiconductor fuse, the XL50F800A is widely cross-listed under the XL50F and FWH-800A designations across major distributors, making it a direct replacement or upgrade for XL50F‑series applications.
