Why Choose the Mersen NH2GG50V355-1 NH Fuse Link?
The Mersen NH2GG50V355-1 is a high-performance NH2 gG low-voltage fuse link designed to protect electrical cables, industrial equipment and power distribution circuits against overloads and short-circuit currents. Manufactured to DIN NH standards, this full-range fuse link provides dependable circuit protection for demanding commercial and industrial electrical installations.
With a rated current of 355 A, a rated voltage of 500 V AC and a 250 V DC rating, the NH2GG50V355-1 is suitable for high-current distribution circuits, switchgear and industrial machinery. Its gG operating characteristic allows it to interrupt currents ranging from sustained overloads to severe short-circuit faults.
The fuse link features isolated gripping lugs, plain blade terminals and a durable ceramic body for reliable electrical and mechanical performance. Its double indication system provides clear visual confirmation when the fuse has operated, while the standard NH2 format supports installation in compatible NH fuse bases and switch-fuse disconnectors.

Reliable Protection for High-Current Electrical Circuits
The Mersen NH2GG50V355-1 uses a full-range gG fuse characteristic to protect cables, conductors and general-purpose electrical equipment. When excessive current passes through the fuse element, the link interrupts the circuit before damaging thermal and electrodynamic stresses can affect downstream components.
Its high breaking capacity makes the fuse suitable for industrial installations where substantial prospective fault currents may occur. The NH2 design provides secure blade-contact installation in compatible fuse bases and switch-fuse equipment. Installation and replacement must be carried out by qualified electrical personnel using suitable NH fuse-handling equipment.
Typical Applications
- Industrial low-voltage distribution boards.
- Electrical cable and conductor protection.
- Switch-fuse units and fuse-switch disconnectors.
- Industrial machinery supply circuits.
- Motor feeder and power distribution circuits.
- Manufacturing and process-control installations.
- Commercial electrical distribution systems.
- Control panels and switchgear assemblies.
