Cooper Bussmann GMD-2.5-R 2.5A Time Delay Cartridge Fuse

Product Description

The COOPER BUSSMANN GMD-2.5-R is a glass-body cartridge time delay fuse rated at 2.5 amps in a compact mini form factor. Measuring 20 mm in overall length and 5 mm in diameter, this fuse provides overcurrent protection for sensitive electronic equipment, control circuits, and low-voltage systems. The time delay design allows short-duration inrush currents to pass without nuisance tripping, while still responding quickly to sustained fault conditions. It is installed by licensed electricians and electronics technicians working on control panels, instrumentation, and light industrial equipment. The glass body allows visual inspection of the fuse element without removal.

This fuse is suited for residential and commercial control circuit applications where a compact, reliable overcurrent protection device is required. Its mini cartridge form factor fits standard mini fuse holders and panel-mount fuse clips used in control boards, HVAC equipment, and electronic instrumentation. The time delay characteristic makes it appropriate for motor-control or transformer-fed circuits where momentary inrush is expected during startup.

Key Features

• 2.5 amp time delay rating handles inrush without nuisance tripping
• Glass cartridge body allows visual inspection of fuse element
• Compact mini size: 20 mm length, 5 mm diameter
• Interrupting rating of 10,000 amps at 125 volts and 100 amps at 250 volts
• Meets UL, CSA, PSE/JET, and RoHS certifications for broad application compliance

Compatibility

Designed as an OEM-style replacement for mini cartridge fuse applications requiring a 20 mm x 5 mm time delay fuse in control panels, instrumentation circuits, and HVAC control boards.

Installation Notes

Installation and replacement of fuses in electrical panels or control circuits should be performed by a qualified electrician in accordance with NEC guidelines. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse matches the amperage, voltage rating, and time delay characteristics required by the original circuit design. Do not substitute a higher-amperage fuse or a fast-acting fuse where a time delay type is specified.
