Why Choose the Mersen H095779 Medium Voltage Fuse?
The Mersen H095779 is a specialised medium voltage cylindrical fuse designed to provide dependable protection for potential transformers, voltage transformers and associated electrical distribution equipment. Also identified by the commercial reference FR20GC83C3,15, it delivers precise current-limiting protection for compatible medium voltage circuits.
Engineered for rapid fault interruption, the H095779 helps restrict the peak current and electrical energy allowed to pass through the protected circuit during a short circuit. This reduces thermal and mechanical stress on transformers, conductors, switchgear and connected monitoring equipment.
With a rated voltage of 8.25 kV AC, a rated current of 3.15 A and a compact 20 × 190 mm cylindrical body, the Mersen H095779 is suitable for compatible fuse holders and transformer protection assemblies. Its low current rating and medium voltage capability make it particularly suitable for instrument transformer and auxiliary circuit protection.
