Five cylindrical glass fuses with metal end caps in a row

Eaton Bussmann

Eaton Bussmann GMC-2-R Glass Fuse 2A 250V Time-Delay 5 Pack

SKU CH-F3HB-Z017D

Five 2 A 250 V AC glass time-delay fuses with 100 A interrupt rating at 250 V AC and 10 kA at 125 V AC

  • Time-delay action prevents nuisance trips from startup surges
  • 2 A at 250 V AC suits many low-voltage circuits
  • 100 A interrupt at 250 V AC clears faults safely
  • Glass body allows quick visual inspection of element
  • Pack of 5 provides ready spares for maintenance

Glass Time-Delay Fuse Pack

The Eaton Bussmann GMC-2-R is a glass-bodied time-delay fuse rated at 2 amperes and 250 volts AC. Each cylindrical fuse measures 20 millimetres long by 5 millimetres in diameter and carries a 100-ampere interrupt rating at 250 volts AC. The five-pack supplies spares for maintenance or multiple circuits.

Suited For Low-Current Protection

These fuses suit low-current AC circuits that experience brief inrush currents, such as small transformers or control gear. They are not for high-current distribution, DC systems above the rated voltage, or applications requiring a rejection-style fuse block.

Fits Standard 5mm Fuse Holders

The 5-millimetre diameter fits common HTB-series fuse blocks and panel-mounted holders without adapters. The time-delay element prevents nuisance opening during startup surges, freeing the installer from frequent replacements. CE, CSA and UL 248-14 markings confirm compliance for North American equipment builds.

Questions about this item

What fuse block series do I need to hold the GMC-2-R 20 mm × 5 mm glass fuse?

The compatible fuse block series is HTB, which accepts the 20 mm length and 5 mm diameter of this GMC series fuse.

Will the 100 A interrupt rating at 250 V AC protect the same circuits as my existing Littelfuse 239 fuses?

Yes, the GMC-2-R is listed as equivalent to Littelfuse 239 and Mersen GSC, with the same 100 A at 250 V AC and 10 kA at 125 V AC interrupt ratings.

How can I verify the fuse is intact after installation?

Check for continuity across the metal end caps with a multimeter; a good fuse shows near-zero resistance through the single-element glass body.
