Eaton MDQ-10 Midget Fuse 10A 250V Small Dimension

Product Description

The EATON MDQ-10 is a 10 amp, 250 volt small-dimension midget fuse designed for overcurrent protection in compact fuseholder applications. The MDQ series is a time-delay, midget-style fuse built to the small-dimension form factor, making it suitable for tight panel spaces and specialty fuseholders that do not accept standard 13/32-inch by 1-1/2-inch midget fuses. Licensed electricians and control-panel technicians install this type of fuse in motor control circuits, HVAC equipment control boards, and other low-amperage branch circuits where reliable overcurrent protection in a space-constrained enclosure is required.

The MDQ-10 is used in residential and light commercial applications where small-dimension fuseholders are specified. Typical installation scenarios include HVAC control panel assemblies, small motor branch circuits, and industrial control equipment requiring a 10 amp, 250 volt rating in a reduced physical form factor. This fuse is not interchangeable with standard 13/32-inch by 1-1/2-inch midget fuses due to its smaller body dimensions.

Key Features

• 10 amp continuous current rating for low-amperage circuit protection
• 250 volt AC rating suitable for standard control and branch circuits
• Small-dimension form factor fits compact fuseholders where standard midget fuses will not seat
• Time-delay design helps prevent nuisance tripping on motor inrush or startup transients
• Lightweight construction at 0.05 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement for small-dimension midget fuseholders rated at 250 volts and 10 amps in HVAC, motor control, and industrial control panel applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing any fuse. Verify the fuseholder is rated for the MDQ small-dimension form factor before installation, as forcing a mismatched fuse into a holder can damage the holder contacts or create an unsafe connection. Do not replace this fuse with a higher-amperage rating without verifying the circuit wiring and load requirements.
