Why Choose the Mersen NH2GG50V40 NH Fuse-Link?
The Mersen NH2GG50V40 is a reliable 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 500 V AC fuse-link range, it is suitable for protecting cables, switchgear, distribution feeders and industrial electrical equipment.
The NH2GG50V40 combines a high breaking capacity with effective current-limiting performance, helping reduce the thermal and mechanical effects of electrical faults. Its durable ceramic body and brass blade terminals provide dependable operation, while the double indication system allows maintenance personnel to identify an operated fuse quickly.
With a rated current of 40 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, this NH Size 2 fuse-link is suitable for industrial switchboards, commercial distribution systems and OEM electrical assemblies. Its standard DIN NH design enables installation in compatible NH2 fuse bases and switch-disconnectors.

Reliable Protection for Low-Voltage Circuits
The Mersen NH2GG50V40 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, making it suitable for a broad selection of general electrical distribution applications.
During a severe fault, the fuse-link limits the peak current and total energy allowed to pass through the circuit. This helps reduce thermal stress, mechanical forces and potential equipment damage while supporting safe and dependable power distribution.

- 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.
