Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann GDC-100MA Glass Fuse 100mA 250V AC 5 PK

SKU CH-T2V9-PGQM4

Pack of five 20 mm glass time-delay fuses rated 100 mA at 250 V AC with a 35 A interrupt rating

  • Protects circuits with 100 mA time-delay glass fuse
  • Handles surges up to 35 A interrupt rating at 250 V AC
  • Fits standard 20 mm x 5 mm cylindrical fuse blocks
  • Certified to cURus and IMQ safety standards
  • Convenient 5-piece pack for spares or multiple installs

Glass time-delay fuse 100 mA 250 V AC

This pack contains five cylindrical glass fuses rated at 100 mA and 250 V AC. Each fuse measures 20 mm long by 5 mm in diameter and carries a 35 A interrupt rating at 250 V AC. They belong to the GDC series and meet cURus and IMQ safety standards. The time-delay characteristic helps absorb brief inrush currents without nuisance opening.

Suited for low-current protection circuits

These fuses suit technicians and hobbyists protecting low-power equipment such as instrument panels, control boards or small transformer primaries. They are not for high-current mains distribution, automotive blade-fuse blocks or applications requiring a rejection-style fuse body. Buyers needing a faster-acting characteristic or a higher voltage rating should look at a different series.

Check holder compatibility and rating

Verify that your fuse holder accepts a 5 mm × 20 mm cylindrical glass body and is rated for at least 250 V AC. Confirm the circuit’s normal current stays well below 100 mA so the time-delay element can operate correctly. Ensure the available fault current does not exceed the 35 A interrupt rating. Cross-reference the GDC, 218, GDG or S506 series codes if you are replacing an existing part.

Questions about this item

Which fuse holder or fuse block series accepts the 20 mm × 5 mm cylindrical glass body of this GDC-100MA fuse?

The compatible fuse block series listed is HTB, which is designed for 20 mm length by 5 mm diameter cylindrical fuses.

If I replace a Littelfuse 218 or Mersen GDG fuse with this Bussmann GDC-100MA, will the electrical ratings match?

Yes, the GDC-100MA shares the same 100 mA, 250 V AC rating and 35 A interrupt rating at 250 V AC as the Littelfuse 218 and Mersen GDG equivalents.

After installation, how can I confirm the time-delay characteristic is functioning correctly?

The fuse should withstand brief inrush currents above 100 mA without opening, yet interrupt a sustained overcurrent up to 35 A at 250 V AC.
