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

Product Description

The COOPER BUSSMANN GMC-2.5-R is a miniature glass cartridge fuse rated at 2.5 amps with time-delay characteristics. It measures 20 millimeters in overall length and 5 millimeters in diameter, conforming to the standard 5x20mm miniature fuse form factor widely used in electronic controls, low-voltage circuits, and equipment protection applications. The time-delay design allows brief inrush currents to pass without nuisance opening, while still protecting downstream components from sustained overcurrent faults. Electricians and electronics technicians install this fuse type in control boards, instrument panels, power supplies, and similar equipment requiring precise overcurrent protection.

This fuse is suited for use in residential and light commercial control circuits, instrumentation, and electronic equipment where a compact 5x20mm time-delay fuse is specified. The glass body allows visual inspection of the fuse element without removal, simplifying field diagnosis. It is appropriate for circuits operating at up to 250 volts AC where low-amperage overcurrent protection is required.

Key Features

• Time-delay (slow-blow) action tolerates inrush current while protecting against sustained faults
• Rated 2.5 amps at up to 250 volts AC
• Interrupting rating of 100 amps at 250V and 10,000 amps at 125V
• Glass body enables quick visual inspection of fuse element
• Standard 5x20mm cartridge dimensions for broad equipment compatibility
• RoHS compliant; UL Listed, CSA Certified, KC-Mark Certified

Compatibility

Designed as a direct replacement for standard 5x20mm miniature cartridge time-delay fuses in control panels, electronic equipment, and instrumentation that specify a 2.5-amp slow-blow fuse in this form factor.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. Always de-energize and lock out the circuit before replacing any fuse. Confirm that replacement fuse amperage and voltage ratings match the equipment nameplate or schematic requirements exactly. Never substitute a fuse with a higher amperage rating to resolve nuisance opening — investigate and correct the underlying fault first.
