Why Choose the Mersen NH1GG69V80 NH Fuse-Link?
The Mersen NH1GG69V80 is a high-performance NH size 1 gG fuse-link designed to provide dependable full-range protection for low-voltage cables, conductors and industrial electrical equipment. Manufactured to the DIN NH standard, this fuse-link combines an 80 A current rating with operating voltages of up to 690 V AC and 400 V DC.
Its gG operating characteristic provides protection against both overload currents and short circuits, making it suitable for general-purpose distribution and industrial power applications. The fuse-link incorporates a ceramic body, silver-plated copper blade contacts and a high breaking capacity to support reliable interruption of severe fault currents.
The NH1GG69V80 also features live gripping lugs and a double indication system, allowing qualified personnel to identify fuse operation more easily during inspection and maintenance. Its standard NH1 dimensions enable installation in compatible NH fuse bases, switch-fuse units and low-voltage distribution assemblies.

Reliable Protection for Industrial Power Distribution
A gG fuse-link provides full-range protection by safely interrupting both sustained overload currents and high-level short-circuit faults. This helps protect cables, busbars and connected equipment from excessive thermal and mechanical stress while reducing the risk of damage within electrical distribution systems.
The Mersen NH system uses blade-contact fuse-links installed into compatible fuse bases or switch-fuse assemblies. Because NH fuse-links must be selected and replaced according to the circuit design and rated current, installation and maintenance should only be performed by suitably qualified electrical professionals using the correct NH fuse-handling equipment.
Typical Applications
- Low-voltage electrical distribution boards.
- Industrial switchgear and control panels.
- Cable and conductor protection.
- Commercial and industrial power distribution.
- Switch-fuse and fuse-disconnector assemblies.
- Machinery power-supply circuits.
- Infrastructure and utility installations.
