Eaton Bussmann GMC-3-R Glass Fuse 3A 250V

This pack contains five cylindrical glass fuses rated at 3 amps and 250 volts AC. Each fuse uses a time-delay design to tolerate brief current surges without opening. The 20 mm by 5 mm body fits standard fuse holders used in automotive, generator and light industrial equipment. They carry CE, CSA and UL certifications for verified safety compliance.

Suits circuits needing 3 A time-delay protection

Installers protecting control boards, lighting ballasts or small motor circuits will find the 100 A interrupt rating at 250 V AC and 10 kA at 125 V AC appropriate for typical branch circuits. The single-element construction provides reliable overcurrent response. Buyers who need a fast-acting fuse for sensitive semiconductor protection or a higher amperage rating for larger loads should select a different series.

3 A 250 V AC time-delay rating decides fit

The 3 ampere, 250 volt AC time-delay characteristic is the single specification that determines whether this fuse matches the circuit design. Verify the holder accepts a 20 mm by 5 mm cylindrical glass body and that the required interrupt rating meets or exceeds 100 A at 250 V AC. The pack of five provides spares for maintenance without ordering individual pieces.

Questions about this item

How can I verify the fuse is working correctly after installation?

A functioning fuse shows continuity with a multimeter and the protected circuit operates normally without blowing the 3 A, 250 V AC glass element.

What comes in the pack and what additional items are needed for installation?

The pack contains five GMC series glass fuses measuring 20 mm long by 5 mm diameter; a compatible HTB series fuse block must be purchased separately.

Which fuse rating and series should I select for my application?

Choose the GMC-3-R 3 A, 250 V AC time-delay version when your circuit requires a 100 A interrupt rating at 250 V AC or 10 kA at 125 V AC.
