Why Choose the Mersen D081791 Medium-Voltage Fuse?
The Mersen D081791, catalogue reference FR36GD32C25P, is a dependable medium-voltage cylindrical fuse-link designed to protect electrical distribution equipment against damaging short-circuit currents. Rated at 25 A, it is suitable for specialised medium-voltage installations, including public lighting networks, transformer circuits and industrial distribution systems.
Featuring a gLD operating characteristic, the D081791 delivers rapid current-limiting performance when a serious electrical fault occurs. By restricting peak fault current and reducing the energy passed into downstream equipment, it helps minimise thermal and mechanical stress on transformers, switchgear, cables and associated components.
The fuse has a robust 36 × 190 mm cylindrical construction and incorporates a striker for fuse-operation indication or activation of compatible switching equipment. Its durable design and reliable electrical performance make it suitable for new installations, planned maintenance and replacement applications.

Reliable Protection for Electrical Distribution Equipment
Medium-voltage fuse-links interrupt dangerous fault currents before they can cause extensive damage to electrical equipment. The Mersen D081791 limits the peak short-circuit current and reduces the energy transmitted through the circuit, helping protect cables, transformers, switchgear and other connected components.
The integrated striker provides a clear mechanical indication after the fuse has operated and may activate a compatible trip mechanism or auxiliary contact. Correct selection should consider the system voltage, continuous operating current, prospective fault current, fuse dimensions and coordination with other protective devices.
Typical Applications
- Public and industrial lighting distribution networks.
- Medium-voltage transformer circuits.
- Electrical switchgear assemblies.
- Industrial power distribution systems.
- Infrastructure electrical installations.
- Compatible switch-fuse combination units.
