  • Fast-acting protection clears faults quickly
  • 5 A rating matches precise circuit requirements
  • 250 V AC rating suits standard mains voltage
  • 100 A interrupt rating at 250 V AC handles high fault currents
  • 20 mm × 5 mm cylindrical glass body fits standard fuse holders

Glass fuse for 2.5 A circuits

This Eaton Bussmann GMA fuse is a fast-acting glass cartridge rated for 2.5 A at 250 V AC. It suits low-current mains or control circuits in appliances, instrumentation or generator equipment where a cylindrical 20 mm by 5 mm fuse is specified.

Replaces blown GMA or 235 series fuses

It directly substitutes Bussmann GMA, Littelfuse 235 or Mersen GGM parts of the same rating. The upgrade is worthwhile when the original fuse has opened or when a design calls for a 100 A interrupt rating at 250 V AC and 10 kA at 125 V AC.

Fits HTB fuse blocks and similar holders

The non-rejection cylindrical body slides into compatible HTB series fuse blocks or any holder accepting a 20 mm by 5 mm glass fuse. Its single-element construction and CE, CSA, PSE and UL certifications simplify compliance in new builds or maintenance jobs.
