  • Glass cylindrical body fits standard 20 mm holders
  • Pack of five provides ready spares

Product Identity

The Eaton Bussmann GMC-10-R is a glass cartridge fuse rated at 10 amps and 125 volts AC with a 200 amp interrupt rating. It suits technicians and hobbyists protecting low-voltage circuits in automotive, marine or small-appliance applications where a time-delay characteristic prevents nuisance blowing from brief inrush currents.

Sustained Load Behaviour

The time-delay element tolerates temporary overloads such as motor start-up surges without opening, yet interrupts fault currents up to 200 amps at 125 volts AC. The cylindrical glass body allows visual confirmation of the element status after an event. The fuse is not designed for high-voltage DC systems or for circuits requiring fast-acting semiconductor protection.

Installation Checks

Verify that the holder accepts a 20 mm length by 5 mm diameter cylindrical fuse and that the circuit voltage does not exceed 125 volts AC. Confirm the required interrupt rating matches the 200 amp specification and that a time-delay response is appropriate for the load type. The pack contains five identical fuses for spares or multiple circuits.

Questions about this item

How much heat does a 10A glass fuse generate when it runs all day?

A 10A glass fuse carries its rated current with minimal heat rise; normal operation stays well within the 125V AC design limits.

What fuse holder or block do I already need to use these 5mm × 20mm GMC fuses?

They fit standard 5mm × 20mm fuse clips or the compatible HTB fuse-block series.

Can I replace older 239-series or GSC fuses in my existing equipment with these GMC-10-R fuses?

Yes — the GMC-10-R is listed as equivalent to Littelfuse 239 and Mersen GSC series for direct substitution.
