Why Choose the Mersen G1032959 High-Voltage Fuse?
The Mersen G1032959, catalogue number 45DB360V16PTS, is a high-voltage DIN back-up fuse-link designed for reliable protection of medium-voltage transformers. Part of the advanced Mersen Limitor®-PTS range, it combines low power dissipation with an integrated 80 N thermal striker, making it ideal for modern air-insulated and gas-insulated switchgear installations.
Rated at 36 kV AC and 16 A, the G1032959 delivers rapid current-limiting interruption during high fault conditions, helping minimise thermal and mechanical stress on transformers, switchgear and associated electrical equipment. The innovative fuse element design reduces heat generation during normal operation, improving reliability and extending equipment life.
Constructed using a durable ceramic body, pure silver fuse elements and silver-coated copper end caps, the fuse incorporates an integrated 80 N thermal striker that can operate compatible switchgear mechanisms if excessive temperatures develop. Measuring approximately 56 mm in diameter and 537 mm in length, it is designed for installation in compatible DIN medium-voltage fuse holders.
