- Time-delay characteristic prevents nuisance blowing during brief surges
- 10 kA interrupt rating at 125 V AC handles high fault currents safely
- Glass body allows instant visual inspection of element status
- Standard 20 mm × 5 mm cylindrical size fits common fuse holders
- Pack of five provides ready spares for maintenance or replacement
Bussmann GMD-500-R Glass Fuse Pack
This pack contains five cylindrical glass fuses rated at 500 mA and 250 V AC. They suit low-current circuits in automotive, generator or general electrical equipment where time-delay protection is required.
Installation and Common Issues
Each fuse measures 20 mm long by 5 mm diameter and fits standard HTB-series fuse blocks. The non-rejection body allows insertion either way, but the glass tube can crack if forced into a corroded or misaligned holder.
Compatibility Checks Before Ordering
Verify that your circuit demands a 500 mA time-delay element with a 10 kA interrupt rating at 125 V AC or 100 A at 250 V AC. Confirm the holder accepts a 5 mm diameter glass body and that CSA Class 1422-01 or UL 248-14 approval meets local code requirements.

Questions about this item
How do I verify the GMD-500-R fuse is working after installation?
Apply power to the protected circuit; if the equipment operates normally and the glass body shows no darkening or broken filament, the fuse is functioning.
What comes in the package and what must I source separately?
The pack contains five 20 mm x 5 mm glass time-delay fuses; a compatible HTB-series fuse block or holder is sold separately.
Which rating should I choose for a 250 V AC circuit needing 500 mA protection?
Select this GMD-500-R version rated 500 mA at 250 V AC with a 100 A interrupt rating at that voltage.
