Why Choose the Mersen Y1000153 High-Voltage General-Purpose Fuse?
The Mersen Y1000153, catalogue reference 45DG120V16P, is a high-voltage DIN general-purpose fuse-link designed to protect distribution transformers against short-circuit currents and low overcurrents. Part of the proven Mersen Limitor®-G series, it provides reliable protection for high-voltage switchgear, controlgear and electrical distribution systems.
Rated at 12 kV AC and 16 A, the Y1000153 provides current-limiting protection by rapidly interrupting substantial fault currents. This helps prevent the prospective fault current from reaching its maximum peak, reducing thermal, electrical and mechanical stress on transformers, cables and associated high-voltage equipment.
The fuse-link features pure silver fuse elements, silver-plated copper terminals and a robust ceramic body. Its DIN-format fuse dimensions are 65 mm in diameter and 292 mm in length, while the integrated 80 N striker can operate compatible switchgear mechanisms or provide a clear indication after the fuse has operated.
Key Advantages
- General-purpose protection against short circuits and low overcurrents.

General-purpose high-voltage fuse-links such as the Mersen Y1000153 are designed to protect transformers against both substantial short-circuit currents and lower overcurrent conditions. This broader operating range supports dependable transformer protection in high-voltage electrical distribution installations.
During an electrical fault, the pure silver fuse elements operate rapidly within the ceramic body to interrupt the current. The resulting current-limiting action reduces the energy passed into the protected equipment, helping minimise damage to transformers, cables, conductors and switchgear.
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.
