Cooper Bussmann BP/GMA-250MA Glass Tube Fuse 2 Pack

Product Description

The COOPER BUSSMANN BP/GMA-250MA is a fast-acting glass tube fuse rated at 250 milliamps (mA) and 250 volts, packaged in a convenient 2-count carded retail pack. Built to the standard GMA form factor at 5 mm x 20 mm, this fuse is designed for electronic equipment and low-current circuit protection. It opens quickly on overcurrent events, helping protect sensitive electronic components from damage. Licensed electricians, electronics technicians, and service professionals use this fuse type when servicing or repairing control boards, instrumentation, and light electronic assemblies.

The GMA glass tube format is a widely used standard in electronic service applications. This fuse is suited for residential and commercial equipment repair scenarios where low-current branch circuit protection is required. Typical install locations include control boards, audio and electronic testing equipment, power supplies, and similar low-voltage electronic assemblies. The 2-pack carded format is practical for field service kits and bench stock.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. Always de-energize and lock out the equipment before replacing a fuse. Confirm the replacement fuse matches the original current and voltage rating exactly — substituting a higher-rated fuse can void equipment safety compliance and create a fire hazard. Refer to applicable NEC guidelines and the equipment manufacturer service documentation for fuse replacement procedures.
