Cooper Bussmann FWX-10A14F Cartridge Fast-acting Fuse 10A

Product Description

The COOPER BUSSMANN FWX-10A14F is a cartridge-style fast-acting fuse rated at 10 amps and designed for overcurrent protection in electrical systems where rapid response to fault conditions is critical. With an overall length of 2 inches (50.8 mm) and a body diameter of 14.3 mm, this fuse fits standard cartridge fuse holders used across industrial, commercial, and trade electrical applications. Its fast-acting characteristic means it interrupts the circuit quickly upon overcurrent, protecting sensitive downstream components. The FWX-10A14F carries CE, CSA, and UL recognition, making it suitable for installations requiring certified components under applicable electrical codes.

This fuse is used in cartridge fuse holders found in control panels, equipment protection circuits, and branch circuit applications where fast-acting overcurrent protection at the 10A rating is specified. It is appropriate for both residential and light commercial electrical systems as well as industrial control enclosures. Licensed electricians and electrical contractors are the primary installers, though HVAC and other trade technicians may encounter this fuse in equipment control circuits.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Always de-energize and lock out the circuit before replacing any fuse. Confirm the replacement fuse amperage, body size, and fuse timing match the original specification before inserting into the holder. Never install a fuse with a higher amperage rating than what the circuit is designed for.
