Why Choose the Mersen NH2GG69V80 NH Fuse-Link?
The Mersen NH2GG69V80 is a dependable DIN NH gG low-voltage fuse-link designed to provide full-range protection against overloads and short circuits in industrial electrical systems. Rated at 80 A, 690 V AC and 250 V DC, this NH Size 2 fuse-link is suitable for protecting cables, conductors, switchgear and connected electrical equipment.
Part of Mersen's established NH fuse-link range, the NH2GG69V80 combines a standardised blade-contact design with live gripping lugs and a double indication system. The indicators provide clear visual confirmation after operation, while the gripping lugs allow the fuse-link to be handled using a suitable low-voltage HRC fuse replacement device.
Its gG full-range utilisation category enables the fuse-link to protect circuits against sustained overload conditions as well as high-level short circuits. The NH2 format is designed for installation in compatible fuse bases and switch-fuse disconnectors used throughout industrial distribution panels, machinery and control systems.

Reliable Protection for Industrial Distribution Systems
The Mersen NH2GG69V80 uses a calibrated fuse element to interrupt excessive current before it can cause serious damage to cables, switchgear or connected equipment. Its current-limiting action reduces the thermal and electrodynamic stresses generated during short-circuit conditions, supporting safer and more reliable system operation.
Because the fuse-link has a gG full-range characteristic, it can provide protection across the complete fault-current range, from prolonged overloads to severe short circuits. It must be fitted in a compatible NH2 fuse base or switch-fuse disconnector and installed or replaced by a suitably qualified electrical professional.
Typical Applications
- Industrial power distribution systems.
- Low-voltage switchboards and switchgear.
- Cable and feeder circuit protection.
- Machinery and automation control panels.
- Commercial electrical distribution installations.
- Compatible NH2 fuse bases and switch-fuse disconnectors.
