Why Choose the Mersen NH4GG50V1000P-2 NH Fuse-Link?
The Mersen NH4GG50V1000P-2 is a heavy-duty NH gG low voltage fuse-link designed to provide full-range protection against overloads and short circuits in industrial electrical distribution systems. Manufactured to the DIN NH standard, it is engineered to protect cables, conductors, switchgear and connected electrical equipment in installations with high current and fault-level requirements.
As part of the dependable Mersen NH gG fuse-link series with striker indication, the NH4GG50V1000P-2 combines robust ceramic construction with a high breaking capacity for reliable operation in demanding industrial environments. Its integrated striker provides a mechanical indication when the fuse has operated and can support compatible remote signalling or switch-disconnection mechanisms.
With a rated current of 1000 A and a 500 V AC operating voltage, the NH4GG50V1000P-2 is suitable for high-power distribution boards, industrial switchgear, manufacturing facilities and infrastructure systems. Its NH4 format, live gripping tags and solid blade terminals enable installation within compatible DIN NH fuse bases.

Reliable Protection for High-Current Distribution Systems
The Mersen NH4GG50V1000P-2 uses a gG operating characteristic to provide full-range protection from low-level overload currents through to severe short-circuit faults. This helps protect power cables, busbar systems, switchgear and connected equipment while reducing the risk of thermal damage and disruptive electrical faults.
Its 120 kA breaking capacity makes the fuse-link suitable for installations with high prospective short-circuit currents. The integrated striker can provide a clear mechanical indication following operation and may be used with compatible auxiliary signalling or automatic disconnection equipment.
Typical Applications
- High-current industrial distribution boards.
- Low voltage switchgear assemblies.
- Power cable and conductor protection.
- Manufacturing and processing facilities.
- Industrial infrastructure systems.
- Heavy-duty machinery power supplies.
- Commercial and utility distribution equipment.
