FWP-40A14FA FUSE 50AMP 700VOLT

Product Description

The FWP-40A14FA is a 40A, 700V high-speed semiconductor fuse from the Eaton Bussmann FWP series. It is designed to provide ultra-fast protection for sensitive power electronic devices such as IGBTs, SCRs, diodes, rectifiers, inverters, UPS systems, and variable frequency drives. Its low I²t value and high interrupting capacity help minimize damage during short-circuit faults.
