Cooper Bussmann FNQ-R-2 2A Cc Time Delay Cartridge Fuse

Product Description

The COOPER BUSSMANN FNQ-R-2 is a time delay cartridge fuse rated at 2 amps in the CC fuse class. Measuring 1.5 inches in overall length and 10.3 mm in diameter, it is designed for installation in compatible CC-class fuse holders. The time delay characteristic allows the fuse to handle brief inrush currents common in motor and transformer circuits without nuisance tripping, while still protecting against sustained overcurrent faults. This fuse carries UL Listing 248-4 Class CC, CSA Class CC certification, CE Marking, and RoHS compliance, making it suitable for commercial and light industrial control panel applications. Licensed electricians and control panel builders are the primary installers of this component.

The FNQ-R-2 is applied in low-voltage control circuits, motor control centers, HVAC equipment control panels, and branch circuit protection where a Class CC time delay fuse is specified. Its rejection feature ensures it can only be installed in CC-rated fuse holders, preventing accidental substitution with non-current-limiting fuse types. This makes it appropriate for new panel builds and service replacements alike in residential and light commercial electrical systems.

Key Features

• 2-amp time delay rating handles motor inrush without nuisance opens
• CC fuse class with rejection feature prevents misapplication in non-CC holders
• 200 kA interrupting rating at AC RMS provides robust fault protection
• UL Listed 248-4 Class CC (Guide JDDZ, File E4273)
• CSA Class CC certified (Class 1422-01, File 53787-HRC-MISC)
• RoHS compliant and CE certified for broad installation compliance

Compatibility

Designed for use in CC-class fuse holders that accept the standard 1.5-inch cartridge body with a 10.3 mm diameter. The rejection feature limits installation to CC-rated holders only.

Installation Notes

This fuse should be installed by a qualified electrician in accordance with NEC requirements for overcurrent protection. De-energize and lock out the circuit before removing or inserting the fuse. Verify the fuse holder is rated for CC-class fuses before installation. Do not substitute a non-rejection or non-time-delay fuse where a Class CC time delay type is specified by the equipment manufacturer.
