Eaton Bussmann Limitron FNQ-R-17-1/2 17.5A 600V Class CC Time-Delay Fuse

Description

Product Overview
The Eaton Bussmann Limitron FNQ-R-17-1/2 is a Class CC cartridge fuse designed for circuit protection in industrial and commercial electrical systems. Rated at 17.5 amperes, it combines a time-delay response with current-limiting performance to help protect compatible circuits against overloads and short-circuit faults.
