Why Choose the Mersen Y1000130 High-Voltage Transformer Fuse?
The Mersen Y1000130, catalogue reference 45DB120V63PT, is a high-voltage DIN back-up fuse-link designed to protect distribution transformers against the damaging effects of short-circuit currents. As part of the Mersen Limitor®-PT series, it combines reliable current limitation with controlled power dissipation for use in high-voltage switchgear, controlgear and electrical distribution systems.
Rated at 12 kV AC and 63 A, the Y1000130 provides rapid interruption of substantial fault currents before they reach their maximum prospective peak. This current-limiting action helps reduce thermal, electrical and mechanical stress on transformers, cables, conductors and associated high-voltage equipment.
The fuse-link features pure silver fuse elements, silver-coated copper end caps and a robust ceramic body. Its VDE T4 DIN format measures 56 mm in diameter and 292 mm in length, while the integrated 80 N controlled power dissipation striker can operate compatible switchgear mechanisms or indicate when the fuse has operated.

Reliable Protection for High-Voltage Transformers
Back-up fuse-links such as the Mersen Y1000130 are designed to interrupt substantial short-circuit currents above their specified minimum interrupting level. They are commonly coordinated with suitable switching devices or additional protective equipment to provide effective transformer protection across the required fault-current range.
The Limitor®-PT design incorporates controlled power dissipation and an 80 N striker for reliable coordination with compatible switchgear. During a severe fault, the fuse elements operate rapidly to limit the current and reduce the energy passed into the protected transformer and electrical installation.
Typical Applications
- High-voltage distribution transformer protection.
- HV/LV transformer installations.
- Electrical substations and utility networks.
- High-voltage switchgear and controlgear.
- Industrial electrical distribution systems.
- Transformer panels and fused switch combinations.
