Why Choose the Mersen NH1GG40V80 NH Fuse-Link?
The Mersen NH1GG40V80 is a dependable DIN NH gG fuse-link designed to provide full-range overload and short-circuit protection in low-voltage electrical distribution systems. Part of the established Mersen NH gG 400 V AC fuse-link series, it is suitable for protecting cables, feeder circuits, switchgear and industrial electrical equipment.
This fuse-link combines a high breaking capacity with effective current-limiting performance, helping reduce the thermal and electrodynamic effects of severe electrical faults. Its robust ceramic body, silver-plated copper blade contacts and double indication system provide reliable operation while allowing maintenance personnel to identify an operated fuse quickly.
With a rated current of 80 A and a rated voltage of 400 V AC, the NH1GG40V80 is suitable for industrial switchboards, commercial distribution systems and OEM electrical assemblies. Its standard NH Size 1 construction enables straightforward installation in compatible DIN NH fuse bases and switch-disconnectors.

Reliable Protection for Low-Voltage Circuits
The Mersen NH1GG40V80 protects electrical circuits by disconnecting sustained overload currents and high-level short-circuit faults before they can damage cables, switchgear or connected equipment. Its gG characteristic provides full-range protection, allowing the fuse-link to serve as the primary overcurrent protection device in suitable applications.
During a severe fault, the fuse-link limits the peak current and total energy passing through the circuit. This helps reduce thermal stress, electrodynamic forces and potential equipment damage while supporting safe and dependable electrical distribution.
Typical Applications
- Industrial switchboards and distribution panels.
- Low-voltage cable and feeder protection.
- Commercial building electrical systems.
- Motor control centres.
- Industrial machinery and production equipment.
- OEM switchgear and electrical assemblies.
- Infrastructure and utility installations.
