Five glass cylindrical fuses with silver end caps

Bussmann

Bussmann GMC-6.3-R Glass Fuse 6.30A 125V AC 5 PK

SKU CH-ATDF-8K4WZ

Pack of five glass time-delay fuses rated 6.30 A at 125 V AC with 200 A interrupt capacity

  • Time-delay protection prevents nuisance trips
  • 30 A rating suits low-current circuits
  • 125 V AC rating fits standard mains
  • 200 A interrupt capacity clears faults safely
  • Pack of five covers multiple replacements

Glass Fuse 6.30 A 125 V AC

This pack contains five EATON BUSSMANN GMC-series glass fuses rated at 6.30 amps and 125 volts AC. The cylindrical body measures 20 mm long by 5 mm diameter. They are time-delay types with a 200 A interrupt rating at 125 V AC and carry CE, CSA Class 1422-01 and UL 248-14 certifications.

6.30 A Time-Delay Rating

The single specification that decides fit is the 6.30 ampere time-delay rating combined with a 125 V AC voltage limit and a 200 A interrupt capacity. These values must match the circuit protection requirements exactly; a different current rating or a fast-acting characteristic will not provide the correct protection.

For Low-Voltage Control Circuits

Suitable for technicians and maintainers replacing GMC, Littelfuse 239 or Mersen GSC fuses in compatible HTB fuse blocks. Not for circuits exceeding 125 V AC, for applications needing a higher interrupt rating, or for buyers who need a rejection-style or ceramic-body fuse.

Questions about this item

What does the 6.30 A rating mean once the fuse is installed in a circuit?

It means the fuse will carry up to 6.30 A continuously and open when current exceeds that value, protecting the downstream wiring and components.

What does the 125 V AC and 200 A interrupt rating cap in practice?

The fuse is rated for circuits up to 125 V AC and can safely interrupt fault currents up to 200 A at that voltage.

What physical dimensions does the fuse need to fit a holder or block?

The cylindrical glass body measures 20 mm long by 5 mm in diameter, matching the standard 20 mm x 5 mm fuse size used with compatible HTB series blocks.
