Cooper Bussmann FWX-100A Fast-acting Fuse 100A Stud Mount

Product Description

The COOPER BUSSMANN FWX-100A is a flush end, fast-acting fuse rated at 100 amps and designed for stud-mount installations. At 3.125 inches overall length, this fuse provides overcurrent protection in industrial and commercial power distribution circuits. Fast-acting response means the fuse clears fault current quickly, limiting damage to downstream components. It carries CE, CSA, and UL recognition, making it suitable for applications where compliance with recognized safety standards is required. Electricians and maintenance technicians working on power distribution panels, drive systems, and equipment protection circuits will find this fuse appropriate for demanding overcurrent protection duties.

The FWX-100A is suited for stud-mount fuse holders in industrial control panels, power conversion equipment, and commercial electrical distribution systems. Its flush-end body type is designed for use with compatible stud-mount fuse blocks and holders. Applications include motor drive protection, power supply circuits, and equipment branch circuits where fast-acting overcurrent protection is specified.
