The COOPER BUSSMANN BP/GMA-500MA is a fast-acting GMA-type glass fuse rated at 500 milliamps (mA) and 250 volts. Each fuse measures 5mm x 20mm, conforming to the standard GMA cartridge form factor used across a wide range of electronic and low-voltage control circuit applications. Sold as a 2-pack on a retail card, this fuse is designed for overcurrent protection in sensitive electronic equipment where a quick response to fault conditions is required. Electricians, electronics technicians, and HVAC control board service technicians commonly use this fuse type when servicing low-voltage circuits.
The BP/GMA-500MA is suited for use in electronic control panels, instrumentation, and low-voltage equipment requiring a 5mm x 20mm fast-acting glass fuse. The fast-acting (non-time-delay) characteristic makes it appropriate for circuits without high inrush currents, such as resistive loads and sensitive signal circuits. It is commonly stocked as a service replacement for control boards, transformers, and electronic assemblies that use the standard GMA glass fuse footprint.
Designed as a direct replacement for standard 5mm x 20mm GMA-type fast-acting glass fuses rated 500mA and 250 volts in electronic control and low-voltage circuit applications.
Installation should be performed by a qualified electrician or electronics technician. Always de-energize and lockout the equipment before replacing a fuse. Verify the replacement fuse rating matches the circuit specification exactly — substituting a higher-rated fuse can damage equipment or create a safety hazard. Follow applicable NEC guidelines for overcurrent protection when servicing electrical panels or control boards.
