Bussmann FNQ-R-20

Bussmann FNQ-R-20

Overview

The Bussmann FNQ-R-20 is a Class CC current-limiting time-delay fuse designed for line protection, small control transformers, branch circuits, and industrial control applications. With a 20 A current rating and 600 V AC / 300 V DC voltage ratings, it provides dependable protection against overloads and short circuits. Its 200 kAIC interrupt rating at 600 V AC ensures maximum safety in high-fault current conditions.

Built with a dual-element time-delay design, the FNQ-R-20 delivers a 12-second response time at 200% overload, preventing nuisance trips and accommodating inrush currents from motors and transformers. The rejection-style feature prevents misapplication, while the ferrule end x ferrule end connection ensures secure installation.
