Eaton FNQ-9 Midget Time-delay Fuse 9A 500V

Product Description

The EATON FNQ-9 is a midget time-delay fuse rated at 9 amps and 500 volts, designed for branch-circuit and control-circuit overcurrent protection in industrial and commercial electrical systems. The time-delay characteristic allows the fuse to tolerate brief inrush currents without nuisance opening, while still responding quickly to sustained overloads and short-circuit faults. At 0.175 pounds, this compact fuse fits standard 13/32 inch by 1-1/2 inch midget fuse holders. Licensed electricians and controls technicians are the primary installers for this type of protective device.

The FNQ-9 is suited for motor control centers, control panels, HVAC equipment control circuits, and other applications where a 500-volt midget fuse is specified. Its time-delay action makes it appropriate for protecting small motors and transformer primaries where a standard fast-acting fuse would open on harmless inrush. It is commonly used in panelboards, disconnect blocks, and inline fuse holders found in light commercial and industrial equipment.

Key Features

• 9-amp continuous current rating with 500-volt AC rating
• Time-delay action tolerates motor inrush and transformer inrush without nuisance tripping
• Midget form factor fits standard 13/32 inch by 1-1/2 inch fuse holders
• Suitable for branch-circuit and supplementary control-circuit protection up to 500 volts
• Compact, lightweight design at 0.175 pounds

Compatibility

Designed as an OEM-style replacement midget time-delay fuse for use in standard 13/32 inch by 1-1/2 inch fuse holders and fuse blocks rated for 500 volts AC.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before replacing a fuse. Verify the replacement fuse amperage and voltage rating match the original specification exactly before installing. Do not substitute a fast-acting fuse where a time-delay type is specified, as nuisance opening or inadequate protection may result.
