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.

- Industrial switchboards and distribution panels.
- Low-voltage cable and feeder protection.
- Commercial building electrical systems.
- Motor control centres.
- Industrial machinery and production equipment.
