Cooper Bussmann FWX-50A Fast-acting Fuse 50A Stud Mount

Product Description

The COOPER BUSSMANN FWX-50A is a flush end, fast-acting fuse rated at 50 amps with an overall length of 3-3/16 inches. It is designed for stud-mount applications and provides overcurrent protection in industrial and commercial electrical systems. The fast-acting response characteristic makes it well suited for circuits that require immediate interruption upon fault conditions, without the intentional time delay found in slow-blow designs. Licensed electricians and industrial maintenance technicians are the primary installers. CE, CSA, and UL recognition confirm this fuse meets widely accepted safety and performance standards.

The FWX-50A is used in control panels, power distribution boards, and equipment protection applications where a compact, stud-mounted overcurrent device is required. Its flush end body type accommodates installations with tight clearance requirements. The fuse is sold individually and is appropriate for both new installations and direct replacement of worn or blown fuses in existing stud-mount fuse holders rated for this form factor.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit completely before removing or installing the fuse. Verify that the fuse holder is rated for the 50-amp current and the stud-mount form factor before installation. Do not install a fuse with a higher amperage rating than the circuit is designed to handle.
