- 20 mm × 5 mm cylindrical fits standard HTB blocks
Fuse Specification
The Bussmann GMA-1.25-R is a fast-acting glass fuse rated at 1.25A and 250V AC for line protection. It has a cylindrical body measuring 20mm long by 5mm in diameter and carries an interrupt rating of 100A at 250V AC. The fuse meets CE, CSA and PSE standards.
Suitable Applications
This fuse suits circuits that require a 1.25A fast-acting glass fuse in the standard 20mm x 5mm form factor. It is not for circuits that demand a higher current rating or a different fuse size. Buyers who need a rejection-type fuse or a slower time-delay characteristic should look at other series.
Critical Rating
The interrupt rating of 100A at 250V AC and 10kA at 125V AC is the single specification that determines whether this fuse can safely clear a fault on your circuit. Verify that your application’s prospective short-circuit current falls within these limits before installation.

Questions about this item
How long will the 20 mm glass body withstand 1.25 A continuous load before the single element opens?
The fast-acting element is designed to carry 1.25 A at 250 V AC indefinitely and will open only when current exceeds the rated value.
Does the cylindrical glass fuse generate noticeable heat or noise during all-day operation at rated current?
At 1.25 A the fuse runs silently with minimal temperature rise; no active cooling is required.
Which fuse block series must I already have to mount this 5 mm diameter fuse?
The fuse fits the compatible HTB fuse block series for 20 mm × 5 mm cylindrical fuses.
