Why Choose the Mersen T078792 Medium Voltage Cylindrical Fuse?
The Mersen T078792, also identified as 36GJB55V50, is a dependable medium voltage cylindrical fuse designed to protect street lighting networks and specialised electrical distribution 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 T078792 is engineered to interrupt excessive fault currents quickly, helping reduce the thermal and mechanical stresses placed on cables, transformers, switchgear and connected electrical equipment. Its gLJB operating class is intended for specialised medium voltage protection duties where reliable fault clearance and high current limitation are required.
With a rated current of 50 A, a rated voltage of 5.5 kV AC and a robust 36 × 250 mm cylindrical body, the Mersen T078792 is particularly suitable for public lighting infrastructure and medium voltage distribution systems. This version is supplied without a striker and should be installed in a compatible fuse holder selected for the circuit requirements.
