Why Choose the Mersen F1000160 High-Voltage General-Purpose Fuse?
The Mersen F1000160, catalogue reference 45DG240V16P, is a high-voltage DIN general-purpose fuse-link designed to protect distribution transformers and medium-voltage electrical systems against short-circuit currents and low overcurrents. As part of the Mersen Limitor®-G series, it provides broader protection than a conventional back-up fuse and is suitable for coordinated transformer protection applications.
Rated at 24 kV AC and 16 A, the F1000160 is engineered for use in high-voltage switchgear, controlgear and transformer feeder systems. Its current-limiting operation helps reduce the thermal and mechanical energy passed into protected equipment during electrical fault conditions.
The fuse-link is manufactured with a durable ceramic insulating body, pure silver fuse elements and silver-plated copper terminals. An integrated 80 N striker provides clear operation indication and can activate compatible switchgear mechanisms when the fuse operates.

The Mersen F1000160 is designed to protect transformers against both severe short-circuit currents and lower-level overcurrents within its specified operating range. Its current-limiting action restricts the peak fault current and let-through energy, helping minimise damage to transformer windings, conductors and switchgear.
As a general-purpose fuse-link, the F1000160 offers a wider protective operating range than a back-up fuse. Correct selection should still consider transformer rating, magnetising inrush current, prospective fault level, ambient temperature and the requirements of the associated switchgear.
Typical Applications
- Medium-voltage distribution transformer protection.
- Industrial electrical substations.
- Air-insulated switchgear systems.
- Gas-insulated switchgear systems.
- Ring main units and transformer feeders.
- Utility power distribution networks.
- Commercial and infrastructure power systems.
- Renewable-energy transformer installations.
