Mersen G095778 medium voltage potential transformer fuse rated at 8.25 kV AC and 2 A, featuring a compact 20 x 190 mm cylindrical body for compatible transformer and distribution protection applications.
£39.52
The Mersen G095778 is a compact medium voltage potential transformer fuse designed to provide reliable short-circuit protection for voltage transformers, control power transformers and associated medium voltage equipment. Also identified by the commercial reference FR20GC83C2, it is engineered for specialised electrical distribution applications requiring precise low-current protection.
The G095778 uses current-limiting fuse technology to interrupt damaging fault currents rapidly. By restricting the peak current and energy allowed to pass through the circuit, it helps reduce thermal and mechanical stress on transformers, switchgear, conductors and connected equipment.
With a rated voltage of 8.25 kV AC, a rated current of 2 A and a compact 20 × 190 mm cylindrical body, the Mersen G095778 is suitable for compatible medium voltage fuse holders and transformer protection assemblies. Its specialised electrical characteristics make it an effective solution for new installations, maintenance projects and direct replacement applications.
Potential transformers are used to reduce medium voltage signals to safe and measurable levels for metering, monitoring and protection equipment. A correctly selected fuse protects the transformer and connected circuitry by rapidly disconnecting excessive fault currents before serious damage can occur.
The Mersen G095778 combines a low 2 A current rating with an 8.25 kV voltage rating, making it suitable for compatible potential transformer circuits. Its compact cylindrical construction allows it to be installed within purpose-designed fuse holders and medium voltage equipment.
