Cooper Bussmann GMA-10-R Cartridge Fast-acting Fuse 10A

Product Description

The COOPER BUSSMANN GMA-10-R is a cartridge-style, fast-acting fuse rated at 10 amps with an interrupting rating of 200 amps at 125 volts. The body is constructed from glass, measuring 20 millimeters in overall length and 5 millimeters in diameter. Fast-acting fuses respond immediately to overcurrent events without intentional time delay, making them well suited for protecting sensitive electronic components and low-voltage control circuits. Licensed electricians and electronics technicians install this fuse type in control panels, instrumentation, and equipment requiring precise overcurrent protection. It meets UL, CSA, and RoHS certification requirements.

This fuse is designed for use in residential and light commercial control circuits, instrumentation panels, HVAC low-voltage control boards, and electronic equipment where fast response to overcurrent conditions is required. The compact 5 millimeter by 20 millimeter form factor is a widely used international cartridge standard, fitting standard panel-mount fuse holders and in-line fuse holders that accept this size. It is sold individually but must be ordered in a minimum quantity of 5 units.

Compatibility

Designed as a direct replacement for standard 5 millimeter by 20 millimeter fast-acting cartridge fuse holders used in HVAC control circuits, instrumentation, and general electronic equipment applications.

Installation Notes

De-energize the circuit and verify zero voltage at the fuse holder before removing or installing this fuse. Use an appropriately rated fuse puller or insulated tool when servicing live panels to comply with NFPA 70 safe work practices. Never substitute a fuse with a higher amperage rating than specified by the equipment manufacturer. Confirm fuse holder ratings match or exceed the interrupting rating of the replacement fuse.
