Cooper Bussmann FWP-80 Semiconductor Protection Fuse

FWP-80A is a high-speed semiconductor protection fuse from Eaton Bussmann (the successor to Cooper Bussmann) rated for 80 A and up to 700 V, designed to protect DC power electronics from overcurrent events. The common North American ferrule-ended variant is the 22x58 mm FWP-80A22F, and the line includes other end configurations such as blade-ended and BI-indicator versions to fit different installation needs, delivering an interrupting capability up to 200 kAIC at 300 Vdc in typical configurations. This fast-acting fuse is intended for DC bus protection in applications like DC drives, rectifiers, and power converters, where rapid current interruption helps safeguard sensitive semiconductors and improve system reliability.
