Cooper Bussmann GMD-125-R Cartridge Time Delay Fuse 0.13A

Product Description

The COOPER BUSSMANN GMD-125-R is a miniature glass cartridge fuse rated at 0.13 amps with time-delay characteristics, designed for low-level overcurrent protection in electronic control circuits, instrumentation, and light industrial equipment. Measuring 20 mm in overall length and 5 mm in diameter, this fuse fits standard 5x20 mm fuse holders. Its time-delay design tolerates brief inrush currents without nuisance blowing, while still providing reliable protection against sustained overcurrent faults. The glass body allows visual inspection of the fuse element. Electricians and electronics technicians typically install this fuse as a circuit protection component or a direct replacement in existing control panels and equipment.

This fuse is suited for applications requiring a compact 5x20 mm time-delay fuse in low-voltage control circuits, HVAC equipment control boards, electronic instrumentation, telecommunications equipment, and similar light-duty electrical assemblies. Its 125-volt rating and 0.13 A continuous current make it appropriate for sensitive low-current circuits where transient inrush protection is necessary. Installations are common in both residential and commercial equipment using standard international 5x20 mm fuse clip or panel-mount holders.

Key Features

• Time-delay fusing tolerates brief inrush currents without nuisance opens
• Glass body enables quick visual inspection of the fuse element without removal
• 10,000 A interrupting rating at 125 volts for robust short-circuit protection
• Compact 5x20 mm form factor fits widely available standard fuse holders
• RoHS compliant and UL Listed, meeting multiple international certifications
• Mini cartridge fuse type for space-constrained control circuit applications

Compatibility

Designed as an OEM-style replacement for standard 5x20 mm miniature glass cartridge time-delay fuses used in electronic control circuits and low-voltage equipment assemblies.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. Always de-energize and lockout/tagout the equipment before replacing fuses. Confirm the replacement fuse matches the original amperage, voltage, and time-delay rating before inserting into the fuse holder. Never substitute a higher-rated fuse or bypass the fuse holder.
