Pack of five 20 mm glass time-delay fuses rated 630 mA at 250 V AC with 10 kA interrupt at 125 V AC
- Time-delay protection handles brief surges without nuisance blowing
- 630 mA rating at 250 V AC suits low-current circuits
- High 10 kA interrupt rating at 125 V AC clears faults safely
- Compact 20 mm × 5 mm glass body fits standard fuse holders
- Pack of 5 provides ready spares for maintenance
Glass Fuse for Low-Current Protection
This pack contains five cylindrical glass fuses rated at 630 mA and 250 V AC. They are designed for circuit protection in equipment where a time-delay characteristic prevents nuisance opening during brief inrush currents. The non-rejection body style fits standard holders without a keyed notch.
Breaking Capacity Defines Safe Application
The interrupt rating is 100 A at 250 V AC and 10 kA at 125 V AC. This specification determines whether the fuse can safely clear a fault in your specific circuit without rupturing. Verify that the prospective short-circuit current of your application does not exceed these limits.
Fits HTB Series Blocks and Equivalent Series
Each fuse measures 20 mm long by 5 mm diameter and matches the Bussmann GMD, Littelfuse 239 and Mersen GSC series. They install directly into compatible HTB fuse blocks or other holders accepting this 5 x 20 mm form factor. The single-element construction simplifies replacement without additional components.

Questions about this item
What does the 630 mA rating mean when the fuse is installed in a circuit?
The fuse will carry up to 630 mA continuously; if current exceeds that value it will open after a time delay, protecting downstream components.
What does the 10 kA interrupt rating at 125 V AC limit in practice?
It means the fuse can safely break a short-circuit current of up to 10 000 A at 125 V AC without rupturing the glass body.
What physical dimensions must a fuse holder or block accommodate for this fuse?
The fuse is a 20 mm long by 5 mm diameter cylindrical glass body, so the holder must accept that exact length and diameter.
