Why Choose the Mersen F1000114 High-Voltage Back-Up Fuse?
The Mersen F1000114, catalogue reference 45DB240V200P, is a high-voltage DIN back-up fuse-link designed to protect distribution transformers and medium-voltage electrical systems against the damaging effects of short-circuit currents. As part of the Mersen Limitor®-P series, it delivers dependable transformer protection and reliable fault interruption for demanding industrial and utility applications.
Rated at 24 kV AC and 200 A, the F1000114 is engineered for installation within compatible medium-voltage switchgear and transformer protection systems. Manufactured using a ceramic fuse body with pure silver fuse elements and silver-plated copper terminals, it provides excellent electrical performance and long operational life.
The fuse incorporates a standard 80 N striker for mechanical indication and operation of compatible switchgear mechanisms. With a high 63 kA breaking capacity, it rapidly interrupts severe fault currents to minimise damage to transformers, switchgear and associated equipment.

Reliable Protection for Medium-Voltage Transformers
The Mersen F1000114 rapidly interrupts high fault currents before they can cause serious thermal or mechanical damage to transformers and associated switchgear. Its current-limiting characteristics reduce the energy released during fault conditions, helping improve system reliability and minimise equipment damage.
As a back-up fuse-link, the F1000114 is intended for high short-circuit protection and should be coordinated with suitable overload protection. Correct fuse selection should always consider transformer rating, prospective fault current and the requirements of the associated switchgear installation.
Typical Applications
- Medium-voltage distribution transformer protection.
- Industrial substations.
- Utility power distribution systems.
- Air-insulated switchgear.
- Gas-insulated switchgear.
- Ring main units.
- Renewable energy transformer installations.
- Commercial medium-voltage power systems.
