Why Choose the Mersen NH1GG50V355P-2 NH Fuse Link?
The Mersen NH1GG50V355P-2 is a high-performance NH1 gG low-voltage HRC fuse link designed to provide full-range protection against overload and short-circuit currents in demanding industrial power distribution systems. Manufactured by Mersen, this DIN-standard fuse link protects cables, switchgear and electrical equipment operating at up to 500 V AC.
The NH1GG50V355P-2 features an integrated striker mechanism that provides mechanical fuse-operation indication and can actuate compatible auxiliary switches or tripping devices. Its robust NH construction, blade contacts and high breaking capacity support dependable performance in installations where reliable fault interruption and remote status signalling are required.
With a rated current of 355 A and a 120 kA AC breaking capacity, this NH1 fuse link is suitable for protecting high-current feeders, switchboards, industrial machinery and electrical distribution equipment. Its gG utilisation category provides complete protection across the operating range, from sustained overload conditions through to severe short-circuit faults.

Reliable Full-Range Electrical Protection
gG fuse links are designed to protect general-purpose cables, conductors and electrical equipment against both overload and short-circuit currents. When excessive current passes through the circuit, the calibrated fuse element safely interrupts the supply before serious thermal or electrodynamic damage can occur.
When the Mersen NH1GG50V355P-2 operates, its striker is released to provide a clear mechanical response. In compatible equipment, this action can activate a microswitch, alarm circuit or switch-disconnector mechanism, enabling rapid fault indication and coordinated isolation of the affected circuit.
Typical Applications
- Industrial power distribution boards.
- Fuse switch-disconnectors and electrical switchgear.
- High-current cable and feeder protection.
- Manufacturing machinery and production equipment.
- Motor control centres and industrial control panels.
- Commercial and industrial electrical infrastructure.
