Bussmann FNQ-R-4

Bussmann FNQ-R-4

Overview

The Bussmann FNQ-R-4 is a Class CC current-limiting time-delay fuse designed for protecting sensitive electrical equipment and control systems. With a 4 A current rating and 600 V voltage rating, it provides excellent protection against overloads and short circuits. Its 200 kAIC interrupt rating ensures safe operation in high-fault current environments.

This fuse features a time-delay design with a 12-second response at 200% overload, making it ideal for handling temporary inrush currents from motors, transformers, and control circuits without nuisance tripping. The rejection-style feature prevents misapplication, while the ferrule end x ferrule end connection ensures secure installation. Built with a durable melamine tube, the FNQ-R-4 is engineered for long-term reliability in industrial environments.
