Why Choose the Mersen D081607 Medium-Voltage Fuse?
The Mersen D081607, catalogue reference 36GB55V12P, is a dependable medium-voltage cylindrical fuse-link designed to protect transformers, switchgear and industrial distribution equipment against damaging electrical faults. Rated at 12 A, it provides rapid current-limiting protection for specialised medium-voltage circuits where reliable fault interruption is essential.
The D081607 uses a gLB fuse characteristic to provide full-range protection against overload and short-circuit conditions. Its fast operation helps restrict peak fault current and reduce the amount of damaging energy passed into cables, transformers and associated electrical equipment.
Featuring a robust 36 × 250 mm cylindrical format, the fuse is designed for installation in a compatible medium-voltage fuse carrier. An integrated striker provides a mechanical indication when the fuse has operated and can activate compatible auxiliary signalling or switchgear mechanisms.

Reliable Protection for Medium-Voltage Equipment
Medium-voltage fuse-links interrupt excessive current before it can cause severe thermal or mechanical damage to electrical equipment. The Mersen D081607 limits both the peak fault current and the energy transferred through the circuit, helping protect transformers, switchgear, cables and connected components.
The integrated striker supports faster fault identification and may operate a compatible trip mechanism or auxiliary contact. Correct selection should consider the system voltage, continuous current, prospective fault current, fuse dimensions and coordination with other protection devices.
Typical Applications
- Medium-voltage transformer protection.
- Industrial switchgear assemblies.
- Auxiliary transformer circuits.
- Electrical distribution equipment.
- Industrial substations.
- Infrastructure and utility installations.
