Fuse for low-current circuit protection

The Bussmann GDB-80MA is a fast-acting glass fuse rated at 80 mA and 250 V AC. It serves engineers and technicians who need reliable over-current protection for sensitive electronic equipment or control circuits. The cylindrical 20 mm by 5 mm body fits standard fuse holders used in industrial and laboratory environments.

Integration into a fuse holder or block

The fuse mounts in compatible HTB series fuse blocks and requires no special tooling for installation. Its non-rejection design allows quick replacement during maintenance. The single-element construction clears faults rapidly, helping to protect downstream components from damage caused by short circuits or overloads.

Cross-reference equivalents simplify sourcing

The GDB-80MA matches the Bussmann S500, Littelfuse 217 and Mersen GSB series, giving buyers multiple supply options. UL recognition under file E19180 and VDE approval under file 40014109 confirm compliance with recognised safety standards. The pack contains five fuses for spares or multi-point installations.
