MERSEN FUSE 5500 CP GLB 36.250 4 36GB55V4

Why Choose the Mersen T081621 Medium Voltage Cylindrical Fuse?

The Mersen T081621, also identified as 36GB55V4, is a dependable medium voltage cylindrical fuse link designed to protect specialised electrical equipment against damaging short-circuit currents. Manufactured by Mersen Ferraz Shawmut, this Limitor fuse provides rapid current-limiting protection for circuits operating at elevated voltages.

The T081621 is engineered to interrupt excessive fault currents quickly, helping reduce the thermal and mechanical stresses placed on transformers, switchgear, cables and connected electrical equipment. Its robust cylindrical construction supports reliable service in demanding industrial and power distribution installations.

With a rated current of 4 A, a rated voltage of 5.5 kV AC and a 36 × 250 mm cylindrical body, the Mersen T081621 is suited to low-current medium voltage protection duties. This version is supplied without a striker and should be installed in a compatible fuse holder selected for the electrical and mechanical requirements of the system.
