Cooper Bussmann FWP-70B Cartridge Fast-acting Fuse 70A

Product Description

The COOPER BUSSMANN FWP-70B is a cartridge-style fast-acting fuse rated at 70 amps, designed to provide reliable overcurrent protection in electrical distribution and power conversion systems. With an overall length of 4-3/8 inches and a stud mount configuration, this fuse is built for secure installation in demanding industrial and commercial applications. Fast-acting response characteristics make it well-suited for protecting semiconductors, drives, and other sensitive components where rapid interruption is critical. Licensed electricians and industrial maintenance technicians are the primary installers. CE Certified, CSA Component Accepted, and UL Recognized, the FWP-70B meets a wide range of compliance requirements.

This fuse is intended for use in industrial power distribution panels, variable frequency drives, power supplies, and similar equipment requiring fast-acting overcurrent protection. Its stud mount design allows for reliable mechanical and electrical connection in bus-bar and chassis-mounted configurations. The FWP-70B is sold individually but is subject to a minimum order quantity of 5 units, making it appropriate for service fleets, panel shops, and electrical contractors stocking for ongoing work.
