  • Glass cylindrical body fits 20 mm × 5 mm fuse holders
  • Pack of five provides ready spares for maintenance

Glass fuse for 1 A circuits

The Bussmann GDC-1A is a 20 mm by 5 mm cylindrical glass fuse rated at 1 A and 250 V AC with a time-delay characteristic. It carries a 35 A interrupt rating at 250 V AC and meets CE, cURus, IMQ and MITI/JET standards. The pack contains five fuses suitable for low-current line protection in compatible equipment.

Suited for low-current AC protection

This fuse fits applications that require a 1 A time-delay device in a standard 5 × 20 mm glass body, such as control circuits, small power supplies or generator auxiliary circuits. It is not for buyers who need a higher current rating, a faster-acting element, a rejection-style base or a different voltage class than 250 V AC.

Sustained overload behaviour

The time-delay element tolerates brief inrush currents without opening, then clears sustained overloads within its rated interrupt capacity of 35 A at 250 V AC. The glass body allows visual confirmation of the fuse state after a fault event.

Questions about this item

What fuse block series must I already have to install these GDC-1A fuses?

They are designed for the HTB fuse block series, so that block must be present for proper fit.

Will the 35 A interrupt rating at 250 V AC protect older circuits that only need a lower breaking capacity?

Yes, the 35 A interrupt rating exceeds lower requirements and will safely clear faults on those circuits.

How can I confirm the fuse is operating correctly after installation?

The time-delay characteristic allows brief inrush currents without opening; if the circuit runs normally under load, the fuse is working as intended.
