Why Choose the Mersen NH4GG50V1250P-2 NH Fuse Link?
The Mersen NH4GG50V1250P-2 is a high-capacity NH4 size gG fuse link designed to provide full-range protection for electrical cables, equipment and industrial power distribution systems. Rated at 1250 A and 500 V AC, it is engineered for demanding low-voltage installations where dependable overload and short-circuit protection is essential.
Its gG operating characteristic enables the fuse link to interrupt currents across its complete operating range, from sustained overloads to severe short-circuit faults. This allows the NH4GG50V1250P-2 to be used as a primary protective device for suitably rated cables, busbars, switchgear and industrial electrical equipment.
The fuse features live gripping tags, standard NH blade contacts and an integrated striker mechanism. The striker can provide mechanical fuse-operation indication or activate compatible auxiliary signalling equipment, helping maintenance teams identify faults quickly and reduce system downtime.
Key Advantages
- Full-range gG protection against overloads and short circuits.
- 1250 A rated current for high-capacity industrial circuits.
- 500 V AC voltage rating for low-voltage power systems.

Reliable Protection for High-Current Power Systems
The Mersen NH4GG50V1250P-2 protects industrial cables, busbars and electrical equipment by interrupting excessive currents before damaging heat and mechanical forces can build up. Its full-range gG characteristic provides protection against both overload conditions and high-level short circuits.
The integrated striker can interact with compatible microswitches, fuse-switch disconnectors or indication systems to signal when the fuse has operated. The fuse must be installed in correctly rated NH4 equipment and should only be handled by qualified electrical personnel using approved NH fuse replacement tools and suitable personal protective equipment.
Typical Applications
- High-current industrial power distribution systems.
- Main electrical switchboards and distribution panels.
- Busbar and feeder circuit protection.
- Fuse-switch disconnectors and heavy-duty switchgear.
- Manufacturing and processing installations.
- Commercial and industrial electrical infrastructure.
