Why Choose the Mersen J081497 Medium Voltage Fuse?
The Mersen J081497 is a dependable medium voltage cylindrical fuse designed to protect compatible electrical distribution systems against damaging short-circuit currents. Also identified by the commercial reference 55GD55V20, this specialised fuse provides reliable current-limiting protection for industrial, infrastructure and public lighting applications.
Engineered for rapid fault interruption, the J081497 helps restrict the peak current and electrical energy permitted to pass through the protected circuit during a short circuit. This reduces the thermal and mechanical stresses placed on cables, switchgear and connected equipment, supporting improved system safety and reliability.
With a rated voltage of 5.5 kV AC, a rated current of 20 A and a robust 55 × 259 mm cylindrical body, the Mersen J081497 is suitable for compatible medium voltage fuse carriers and electrical equipment. This version is supplied without an integrated striker mechanism, so its physical and electrical compatibility should be confirmed before installation.

Reliable Protection for Medium Voltage Systems
Medium voltage fuses protect electrical infrastructure by interrupting excessive fault currents before they can cause serious damage to cables, switchgear and connected equipment. Their current-limiting action restricts both the peak fault current and the total energy allowed to pass through the protected circuit.
The Mersen J081497 combines a 20 A rating with a durable 55 × 259 mm cylindrical format. It is suitable for maintenance, replacement and new installation projects where its voltage rating, dimensions, fuse characteristic and non-striker configuration match the intended equipment.
