Eaton Bussmann FWP-80A22F 80A 700V 22×58mm High-Speed Semiconductor Fuse

Description

Product Overview
The Eaton Bussmann FWP-80A22F is a high-speed cylindrical fuse from the FWP series, developed for semiconductor and power-electronic circuit protection. Its fast-acting characteristics help protect compatible equipment against damaging overcurrent conditions.
With an 80A current rating, a 700V AC/DC rating and a Class aR utilization category, this fuse is intended for applications that require semiconductor protection rather than general-purpose full-range overload protection. Correct selection depends on the equipment design, fault-current level and manufacturer specifications.
