Why Choose the Mersen NH1GG50V100-1 NH Fuse Link?
The Mersen NH1GG50V100-1 is a high-quality NH1 gG low-voltage HRC fuse link designed to provide full-range protection against overload and short-circuit currents. Rated at 100 A, it is suitable for protecting cables, conductors, switchgear and general-purpose electrical equipment in industrial and commercial power distribution systems.
Engineered for circuits operating at up to 500 V AC or 250 V DC, this DIN-standard fuse link combines dependable current-limiting performance with a high 120 kA AC breaking capacity. Its robust ceramic body and plain brass blade contacts support reliable operation in demanding electrical environments.
The NH1GG50V100-1 also features isolated gripping tags and an integrated double operation indicator. These features improve handling safety and allow maintenance personnel to identify an operated fuse quickly during inspection and fault-finding procedures.

Reliable Full-Range Circuit Protection
The gG characteristic makes the Mersen NH1GG50V100-1 suitable for protecting general-purpose electrical circuits across the full fault-current range. It responds to sustained overload conditions as well as high short-circuit currents, helping prevent excessive heating and damage to cables, conductors and connected equipment.
During a severe fault, the fuse element melts and safely interrupts the current within the ceramic body. Its current-limiting action helps reduce the peak let-through current and energy transferred to downstream components, limiting thermal and electrodynamic stress within the installation.
Once the fuse has operated, the double indicator provides a clear visual status indication. The isolated gripping tags allow the fuse link to be handled using an appropriate NH replacement handle while reducing the risk of contact with live metal gripping surfaces.
Typical Applications
- Industrial power distribution boards.
- Commercial switchboards and panelboards.
- Cable and feeder protection.
- Fuse switch-disconnectors.
