Eaton FNQ-R-2-1/4 Midget Time-delay Fuse 2.25A 600V

Product Description

The EATON FNQ-R-2-1/4 is a midget time-delay fuse rated at 2-1/4 amps and 600 volts, designed for overcurrent protection in control circuits, motor branch circuits, and low-amperage electrical systems. Its time-delay characteristic allows it to ride through harmless inrush current spikes without nuisance tripping, while still responding quickly to sustained fault conditions. Electricians and controls technicians install this fuse in fusible disconnect blocks, control panels, and small motor control applications where space is limited and precise amp ratings are required.

This midget fuse fits standard 13/32-inch by 1-1/2-inch midget fuse holders commonly found in industrial control panels, HVAC equipment, and commercial electrical systems. The 600-volt rating makes it suitable for both single-phase and three-phase control circuit applications. Its compact form factor is appropriate for equipment where panel space is at a premium and where branch-circuit or supplemental overcurrent protection is mandated by NEC requirements.

Key Features

• 2-1/4 amp rating for precise overcurrent protection in low-amperage control circuits
• 600-volt rating suitable for single-phase and three-phase applications
• Time-delay design tolerates motor inrush and transformer magnetizing current without nuisance opens
• Midget form factor fits standard 13/32-inch by 1-1/2-inch fuse holders
• Supplemental and branch-circuit overcurrent protection per NEC guidelines

Compatibility

Designed as an OEM-style replacement for midget time-delay fuses used in residential and commercial control panels, HVAC equipment, and industrial motor control circuits requiring a 13/32-inch by 1-1/2-inch midget fuse form factor.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lockout/tagout the circuit before removing or installing any fuse. Use a properly rated fuse puller when handling midget fuses to avoid contact with energized components. Verify the replacement fuse amp rating and voltage rating match the circuit requirements exactly before restoring power.
