The COOPER BUSSMANN GDB-3.15A is a fast-acting glass cartridge fuse rated at 3.15 amps. It is designed for overcurrent protection in low-voltage electronic and electrical equipment where rapid response to fault conditions is critical. The cylindrical glass body measures 20 millimeters in overall length and 5 millimeters in diameter, conforming to the IEC 60127-2 standard miniature fuse form factor. Licensed electricians and electronics technicians use this fuse in control circuits, instrumentation panels, and small appliance applications requiring precise, fast-blow protection.
The GDB-3.15A is suited for residential and commercial electronic equipment, HVAC control boards, instrumentation, and other low-current applications where a fast-acting fuse is specified. Its compact mini cartridge form fits standard 5 x 20 millimeter fuse holders found in a wide range of domestic and international equipment. The glass body allows quick visual inspection of the fuse element to confirm open or intact status without removal.
Designed as a standard 5 x 20 millimeter fast-acting cartridge fuse replacement for electronic equipment, control panels, and instruments that specify an IEC 60127-2 miniature fuse at 3.15 amps.
Always de-energize and lock out the equipment before replacing any fuse. Verify that the replacement fuse amperage and timing rating match the circuit requirements exactly — substituting a fuse with a different rating can damage equipment or create a safety hazard. Use an appropriate fuse puller when removing the fuse from spring-clip or drawer-type holders to avoid damaging the glass body or holder contacts. Fuse replacement in listed electrical equipment should comply with applicable NEC guidelines and the equipment manufacturer's service documentation.
