Why Choose the Mersen G1000161 High-Voltage Fuse?
The Mersen G1000161, also identified by catalogue number 45DG240V25P, is a high-voltage DIN fuse-link designed to protect medium-voltage transformers against damaging short-circuit currents and low overcurrents. It forms part of the proven Mersen Limitor®-G general-purpose fuse range, developed for dependable operation within high-voltage switchgear, controlgear and electrical distribution systems.
Rated at 25 A and 24 kV AC, this fuse provides effective current-limiting protection for transformer installations. Its fast interruption characteristics help reduce the thermal and mechanical stresses placed on transformers, switchgear and associated electrical equipment during fault conditions.
The G1000161 features a robust ceramic fuse body, pure silver fuse elements and silver-coated copper end caps. It also incorporates an 80 N striker, allowing compatible switchgear mechanisms or indication systems to respond when the fuse operates. Its DIN-format construction measures approximately 88 mm in diameter and 442 mm in length.

Reliable Protection for Medium-Voltage Transformers
High-voltage fuse-links protect transformers by interrupting excessive current before it causes severe thermal or mechanical damage. The Mersen G1000161 provides general-purpose protection against both high short-circuit currents and lower overcurrent conditions within its specified operating range.
Its current-limiting performance helps restrict the peak fault current and energy passed into the protected installation. This can reduce stress on transformer windings, conductors, busbars and switchgear components while supporting improved system reliability.
Typical Applications
- Medium-voltage transformer protection.
- High-voltage switchgear assemblies.
- Transformer feeder panels.
- Industrial electrical distribution networks.
- Commercial and infrastructure power distribution systems.
- Medium-voltage substations and controlgear.
- Fuse-switch combination units.
