Why Choose the Mersen NH1GG50V80 NH Fuse Link?
The Mersen NH1GG50V80 is a dependable NH gG low voltage fuse link designed to provide full-range overcurrent protection for industrial cables, conductors, switchgear and electrical distribution equipment. As part of the established Mersen NH fuse-link range, it protects circuits against both sustained overloads and high short-circuit currents.
This fuse link combines an 80 A rated current with voltage ratings of 500 V AC and 250 V DC. Its double operating indicator provides clear visual confirmation when the fuse has operated, helping maintenance personnel locate faults quickly and reduce system downtime.
With its NH Size 1 format, 30 mm body width and live gripping lugs, the NH1GG50V80 is suitable for installation in compatible DIN NH fuse bases. Its robust industrial construction makes it an effective protection solution for distribution panels, motor control centres and machinery electrical systems.

Reliable Protection for Industrial Electrical Circuits
The Mersen NH1GG50V80 uses a gG operating characteristic to protect cables and general electrical equipment across the complete overcurrent range. It responds to persistent overloads as well as severe short circuits, helping prevent thermal damage, insulation failure and disruption to connected equipment.
The fuse link must be installed in a correctly rated NH1 fuse base and replaced using an appropriate low voltage HRC fuse puller. Because NH fuse systems do not inherently prevent the installation of a fuse with an unsuitable current rating, selection and replacement should only be carried out by qualified electrical professionals.
Typical Applications
- Industrial power distribution systems.
- Electrical switchboards and distribution panels.
- Motor control centres.
- Protection of cables and conductors.
- Industrial machinery and OEM equipment.
- Commercial and infrastructure electrical installations.
