Cooper Bussmann GMD-2-R 2A Time Delay Cartridge Fuse

Product Description

The COOPER BUSSMANN GMD-2-R is a miniature glass cartridge fuse rated at 2 amps with a time-delay response characteristic. It measures 20 mm in overall length and 5 mm in diameter, conforming to the standard IEC 5x20 mm form factor widely used in electronic controls, appliances, and low-voltage circuit protection applications. The time-delay design allows brief inrush currents to pass without nuisance opening, while still protecting against sustained overloads and short circuits. The glass body allows visual inspection of the element without removal. This fuse is installed by electricians and electronics technicians in panel-mount fuse holders and PCB-mount clips.

The GMD-2-R is suited for residential and commercial low-voltage control circuits, instrumentation, HVAC control boards, and small appliance protection where a 5x20 mm time-delay fuse is specified. Its interrupting rating of 10,000 amps at 125 volts and 100 amps at 250 volts covers the majority of single-phase low-voltage branch circuits and control wiring applications. The mini cartridge format makes it a direct fit in standard 5x20 mm panel and inline fuse holders.

Key Features

• Time-delay action tolerates motor start and transformer inrush without nuisance tripping
• Glass body enables quick visual inspection of the fuse element
• 10,000 amp interrupting rating at 125 volts for robust short-circuit protection
• Standard IEC 5x20 mm cartridge format fits widely available holders and clips
• Meets UL, CSA, PSE/JET, and RoHS certifications for broad application compliance

Compatibility

Designed as a direct replacement for standard IEC 5x20 mm time-delay miniature cartridge fuses in low-voltage control and electronic circuit applications.

Installation Notes

Installation should be performed by a qualified electrician or technician. De-energize and verify zero voltage on the circuit before removing or installing any fuse. Ensure the replacement fuse rating exactly matches the circuit protection requirements specified by the equipment manufacturer. Fuse holders must be rated for the voltage and current of the application per NEC guidelines.
