Cooper Bussmann FNQ-1-6/10 Cartridge Time Delay Fuse

Product Description

The COOPER BUSSMANN FNQ-1-6/10 is a general-purpose cartridge time delay fuse rated at 1.6 amps and 500 volts with a 10 kA AC interrupting rating. Built with a fiber body in a standard cartridge form factor, it is designed for mounting in a compatible fuse holder. The orange color coding aids quick visual identification during service. Electricians and maintenance technicians install this fuse to protect low-current branch circuits, control circuits, and equipment from overcurrent faults in commercial and industrial applications.

This fuse is suited for use in residential, commercial, and light industrial electrical systems where time delay characteristics are required to ride through brief inrush currents without nuisance tripping. The 10.3 mm diameter and 38.1 mm overall length fit standard midget fuse holders. Typical applications include motor control circuits, HVAC control panels, and other low-amperage control wiring scenarios where a delayed response to transient surges is necessary to maintain system stability.

Compatibility

Designed as an OEM-style replacement cartridge time delay fuse for use in standard midget fuse holders accepting a 10.3 mm diameter, 38.1 mm length cartridge.

Installation Notes

Installation and replacement should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and verify the circuit is dead before removing or inserting a fuse. Confirm the replacement fuse matches the original amperage and voltage rating before reinstalling. Use an appropriate fuse puller when removing cartridge fuses from live-rated holders to avoid contact with energized components.
