Why Choose the Mersen Y209367 High-Voltage Transformer Fuse?
The Mersen Y209367, catalogue reference 45DB360V32PD, is a high-voltage DIN back-up fuse-link engineered to protect distribution transformers against the damaging effects of short-circuit currents. As part of the trusted Mersen Limitor®-PD series, it delivers dependable current-limiting protection for high-voltage switchgear, controlgear and electrical distribution systems.
Rated at 36 kV AC and 31.5 A, the Y209367 rapidly interrupts severe fault currents before they reach their maximum prospective peak. This reduces thermal, electrical and mechanical stresses on transformers, cables and associated high-voltage equipment, helping improve system reliability and minimise equipment damage.
Manufactured using a durable ceramic body, pure silver fuse elements and silver-plated copper end caps, the fuse-link measures 65 mm in diameter and 537 mm in length. An integrated 80 N striker enables operation of compatible switchgear mechanisms or provides clear indication after fuse operation.

Reliable Protection for High-Voltage Transformers
The Mersen Y209367 is designed to provide dependable protection for distribution transformers operating within medium- and high-voltage electrical networks. Its current-limiting characteristics reduce the energy released during severe electrical faults, helping extend the service life of transformers, switchgear and associated infrastructure.
As a back-up fuse-link in accordance with IEC 60282-1, it is intended to interrupt high fault currents above its specified minimum breaking current and should be coordinated with suitable switching equipment to provide comprehensive transformer protection.
Typical Applications
- Distribution transformer protection.
- Medium- and high-voltage substations.
- Industrial electrical distribution systems.
- High-voltage switchgear and controlgear.
- Utility power distribution networks.
- Renewable energy distribution equipment.
