Cooper Bussmann FWX-70A Flush End Fast-acting Fuse 70A

Product Description

The COOPER BUSSMANN FWX-70A is a flush end fast-acting fuse rated at 70 amps, designed for stud-mount installation in industrial and commercial power distribution systems. Fast-acting fuses like the FWX-70A respond immediately to overcurrent events, providing tight circuit protection where time-delay characteristics are not required. The stud-mount body style allows secure, low-resistance termination directly to bus bars or mounting blocks. Weighing 0.32 pounds, this fuse carries CE, CSA, and UL recognition, making it suitable for installations that require compliance with North American and international electrical standards. It is installed by licensed electricians and electrical contractors working on distribution panels, power conversion equipment, and related assemblies.

The FWX-70A is suited for use in industrial control panels, power distribution boards, and electrical enclosures where fast-acting overcurrent protection at 70 amps is required. Its stud-mount configuration makes it a practical choice for bus bar assemblies and high-current terminal blocks commonly found in commercial and industrial facilities. The flush end body style simplifies mounting and replacement in confined panel spaces.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing any fuse. Verify that the fuse holder or stud-mount terminal is rated for the amperage and voltage of the circuit being protected. Do not replace a fast-acting fuse with a time-delay type without confirming that the new rating is appropriate for the load.
