Bussmann GMA-1.5-R Glass Fuse 1.5 A 250 V AC

Glass fuse for low-current circuits

The Bussmann GMA-1.5-R is a 1.5 A, 250 V AC fast-acting glass fuse in the GMA series. It uses a cylindrical 20 mm by 5 mm body with a single element and non-rejection contacts. The fuse carries CE, CSA and PSE markings along with UL recognition. It suits equipment that requires a 1.5 ampere glass fuse rated for 250 V AC.

Verify voltage and interrupt rating first

Check that your circuit operates at or below 250 V AC and that the available fault current does not exceed 100 A at that voltage. At 125 V AC the interrupt rating rises to 10 kA, so confirm which voltage applies. Ensure the holder accepts a 20 mm by 5 mm cylindrical fuse and that a fast-acting characteristic matches the protection scheme.

Fits HTB fuse blocks and equivalent series

The fuse mounts in compatible HTB fuse blocks and cross-references Littelfuse 235 and Mersen GGM series. Its glass body allows visual inspection of the element after a fault. The fast-acting response limits energy let-through on sensitive loads, while the non-rejection design fits standard clips without a keyed block. No additional hardware is required beyond a suitable holder.
