Bussmann GMD-1-R Glass Fuse 1A 250V 10kA 125V 5pk
Pack of five 1A glass time-delay fuses rated 250V AC with 10kA interrupt at 125V AC
- Time-delay design protects circuits from brief surges
- 1 A rating at 250 V AC suits low-current applications
- High 10 kA interrupt capacity at 125 V AC handles severe faults
- 5 mm × 20 mm glass body fits standard fuse holders
- Pack of five gives ready spares for maintenance
Glass Fuse 1A 250V AC 5 Pack
This pack contains five cylindrical glass fuses rated at 1 ampere and 250 volts AC. Each fuse features a time-delay characteristic and a non-rejection body style measuring 20 millimetres in length by 5 millimetres in diameter. They provide an interrupt rating of 100 amperes at 250 volts AC and 10 kiloamperes at 125 volts AC.
Suits Low-Current Circuit Protection
These fuses suit technicians and hobbyists protecting low-current circuits in automotive, generator or general electrical equipment. They are not suitable for circuits requiring a higher amperage rating, a rejection-type body or a faster-acting blow characteristic. Buyers needing a different voltage or interrupt rating should select an alternative series.
Simple Fuse Block Installation
Installation consists of inserting the fuse into a compatible HTB series fuse block or equivalent 5-millimetre diameter holder. The glass body allows visual inspection of the element after a fault. A common error is exceeding the 1 ampere rating or using a holder not rated for the 10 kiloampere interrupt capacity at 125 volts AC.

Questions about this item
What fuse holder or block series accepts the 20 mm by 5 mm cylindrical glass body of this GMD-1-R fuse?
The compatible fuse block series listed is HTB, which matches the 20 mm length and 5 mm diameter of this fuse.
Can this 1 A time-delay fuse replace a Littelfuse 239 or Mersen GSC in existing equipment?
Yes, the specifications list Littelfuse 239 and Mersen GSC as equivalent series, so it can serve as a direct replacement.
How do I verify the fuse is intact after installing it in a 250 V AC circuit?
Check for continuity with a multimeter; a good fuse will show low resistance, while a blown fuse will show an open circuit.
