Cooper Bussmann BP/GMA-1A 1A 250V Gma Glass Fuse 2 Pack

Product Description

The COOPER BUSSMANN BP/GMA-1A is a Type GMA fast-acting glass fuse rated at 1 amp and 250 volts. Measuring 5mm x 20mm, this fuse provides overcurrent protection in electronic equipment and low-voltage control circuits. Each carded retail pack contains two fuses, making it a practical service item for techs who need a spare on hand. The fast-acting response characteristic means the fuse clears faults quickly, protecting sensitive electronic components from sustained overcurrent. HVAC technicians, electricians, and electronics service professionals install this type of fuse in control boards, instrumentation, and small appliance circuits.

The BP/GMA-1A is suited for residential and light commercial electronic applications where a 5mm x 20mm fast-acting fuse is specified. Common install scenarios include replacement of blown fuses in HVAC control panels, electronic instrumentation, audio equipment, and similar low-current circuits. The carded two-pack format is designed for retail and service-counter distribution, allowing technicians to replace one fuse and retain a spare for the next call.

Installation Notes

Power down and de-energize the equipment completely before replacing any fuse. Verify the replacement fuse matches the amperage, voltage, and speed rating specified on the equipment nameplate or schematic before installation. Use an insulated fuse puller when removing fuses from panel-mount holders to avoid contact with energized components. Always investigate and correct the root cause of a blown fuse before returning equipment to service.
