Glass fuse for low-voltage circuits
This pack contains five Eaton Bussmann GMA series glass fuses rated at 4 A and 125 V AC. They suit equipment that requires a fast-acting, single-element fuse in a 20 mm by 5 mm cylindrical body. The non-rejection style fits compatible HTB series fuse blocks without a keyed holder.
Glass body and cylindrical mounting
The glass tube lets you inspect the element visually after a fault. A 10 kA interrupt rating at 125 V AC means the fuse can clear high short-circuit currents safely. The 20 mm length and 5 mm diameter match the standard GMA form factor used in many panel-mounted fuse blocks.
Check voltage and holder compatibility
Verify that your circuit operates at or below 125 V AC and that the fuse block accepts a non-rejection 5 mm diameter fuse. Confirm the 4 A rating matches the protection requirement of the load. The pack provides five pieces for spares or multiple circuits.

Questions about this item
What does the 10kA interrupt rating at 125V AC mean for this fuse?
It means the fuse can safely break a fault current up to 10kA at 125V AC without rupturing, protecting the circuit during a severe short circuit.
What are the physical dimensions needed for a holder to accept this GMA fuse?
The fuse body is 20 mm long and 5 mm in diameter, matching the standard 5×20 mm cylindrical size used in compatible HTB series fuse blocks.
How do you install these fast-acting glass fuses, and what common mistake should be avoided?
Insert each fuse into a suitable 5×20 mm holder until fully seated; do not solder directly to the glass body or use a holder rated below 125V AC and 10kA interrupt capacity.
