Why Choose the Mersen G1006095 High-Voltage Fuse?
The Mersen G1006095, also identified by catalogue number 45DB120V10P-3, is a high-voltage DIN back-up fuse-link developed to protect medium-voltage transformers against damaging short-circuit currents. It belongs to the established Mersen Limitor®-P range of transformer fuses without controlled power dissipation.
Rated at 10 A and 12 kV AC, the G1006095 delivers rapid, current-limiting interruption during severe electrical faults. By restricting the peak fault current and clearing energy, the fuse helps reduce thermal and mechanical stress on transformer windings, cables, busbars and associated switchgear.
The fuse has a robust ceramic body with pure silver fuse elements and silver-plated copper terminals. Its integrated 80 N standard striker can activate a compatible switch-disconnector or indication mechanism when the fuse operates. The DIN-format fuse measures 63 mm in diameter and 442 mm in length, making it suitable for compatible medium-voltage fuse clips and switchgear assemblies.

The Mersen G1006095 is classified as a back-up fuse under IEC 60282-1. It is designed to interrupt high fault currents above its specified minimum interrupting rating and should be coordinated with suitable overload protection to provide comprehensive transformer protection.
When a severe short circuit occurs, the fuse elements melt rapidly and restrict the current before it reaches its full prospective peak. This reduces the let-through energy and helps protect transformer windings, conductors, switchgear and other valuable components from extensive fault damage.
Typical Applications

- High-voltage switchgear and controlgear.
- Transformer feeder panels.
- Fuse-switch combination units.
- Industrial electrical distribution systems.
- Commercial and infrastructure substations.
- Utility power distribution networks.
- Indoor and outdoor medium-voltage installations.
