Cooper Bussmann FNQ-R-9 9A Cc Time Delay Cartridge Fuse

Product Description

The COOPER BUSSMANN FNQ-R-9 is a time delay cartridge fuse rated at 9 amps in the CC fuse class. It is designed for general-purpose overcurrent protection in control circuits, HVAC equipment, and light commercial electrical panels. The rejection feature prevents cross-installation with non-CC class fuses, maintaining circuit protection integrity. At 1.5 inches in overall length and 10.3 mm in diameter, it fits standard CC-class fuse holders. Licensed electricians and HVAC technicians install this fuse during routine service or panel work where time delay characteristics are required to ride through motor inrush currents without nuisance tripping.

The FNQ-R-9 is suited for residential and light commercial applications where CC-class fusing is specified. Common installations include HVAC control circuits, motor branch circuits, and equipment requiring time delay overcurrent protection. The CC class form factor and rejection feature make it a direct fit for dedicated CC fuse holders found in supplemental and branch circuit protection applications. It ships in a minimum order quantity of 5 units per package.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC. Always de-energize and verify the circuit is dead before replacing any fuse. Use an appropriately rated fuse puller when removing or inserting the fuse in its holder. Confirm the replacement fuse amperage and class match the circuit requirements before energizing.
