Cooper Bussmann FWX-3A14F Cartridge Fast-acting Fuse 3A

Product Description

The COOPER BUSSMANN FWX-3A14F is a cartridge-style fast-acting fuse rated at 3 amps, designed to provide rapid overcurrent protection in electrical systems where component damage from sustained fault current must be minimized. At 2 inches (50.8 mm) overall length and 14.3 mm in diameter, this fuse fits standard cartridge fuse holders used across industrial, commercial, and trade electrical applications. Its fast-acting response characteristic means it clears fault conditions with minimal delay, making it appropriate for protecting sensitive equipment, instrumentation circuits, and power distribution components. Licensed electricians and electrical technicians are the primary installers of this product.

This fuse is suited for use in cartridge fuse holders requiring a 14.3 mm diameter body and 50.8 mm overall length. Typical applications include control panel overcurrent protection, industrial equipment branch circuits, and electrical distribution systems where fast-acting fuse characteristics are specified. It is sold individually and carries CE and UL recognition, making it appropriate for installations subject to North American and international electrical standards.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lockout/tagout the circuit before removing or installing any fuse. Use an insulated fuse puller rated for the voltage of the circuit when extracting cartridge fuses from live panels during serviced conditions. Verify fuse holder rating matches or exceeds the fuse interrupt and voltage specifications before installation.
