Why Choose the Mersen T081483 Medium Voltage Cylindrical Fuse?
The Mersen T081483, also identified as 55GD55V25P, is a premium medium voltage current-limiting fuse engineered to provide dependable protection for transformers, switchgear, street lighting installations and medium voltage distribution systems. Manufactured by Mersen Ferraz Shawmut, this IEC fuse delivers rapid fault interruption while minimising thermal and mechanical stress on protected equipment.
Designed for demanding industrial and utility environments, the T081483 incorporates an integrated striker (Percuteur) to provide mechanical indication when the fuse operates and to interface with compatible tripping or signalling mechanisms. Its current-limiting design helps reduce fault energy, improving equipment protection and system reliability.
With a rated current of 25 A, a rated voltage of 5.5 kV AC and a 55 × 259 mm cylindrical body, the Mersen T081483 is particularly suitable for public lighting networks, transformer protection and medium voltage distribution equipment requiring reliable IEC-compliant protection.
