Bussmann FRS-R-40

Bussmann FRS-R-40

Overview

The Bussmann FRS-R-40 is a Class RK5 dual-element time-delay fuse designed for industrial and commercial circuit protection. With a 40 A current rating and voltage ratings of 600 V AC and 250 V DC, it delivers reliable overload and short-circuit protection. Its 200 kAIC interrupt rating at 600 V AC ensures dependable fault clearing in high-energy environments.

Built with a ferrule end x ferrule end connection, the FRS-R-40 provides secure installation in standard fuse holders. Its dual-element time-delay design delivers a 10-second response at 500% overload, making it ideal for motors, transformers, and inductive loads by preventing nuisance tripping during inrush conditions.
