Why Choose the Mersen NH22GG50V250-1 NH Fuse Link?
The Mersen NH22GG50V250-1 is a high-performance NH2 gG low-voltage HRC fuse link designed to provide dependable full-range protection for industrial cables, electrical equipment and power distribution systems. Manufactured by Mersen, this DIN-standard fuse link safely interrupts overload and short-circuit currents in demanding commercial and industrial installations.
The NH22GG50V250-1 features a durable ceramic insulating body, plain brass blade terminals and isolated gripping lugs for safer professional handling. Its integrated double indication system allows maintenance personnel to identify an operated fuse quickly, helping reduce fault-finding time and equipment downtime.
With a rated current of 250 A, a 500 V AC rating and a 250 V DC rating, this NH2 fuse link is suitable for protecting industrial feeders, switchboards, machinery circuits and electrical distribution infrastructure. Its gG operating characteristic provides full-range protection from the lowest applicable fusing current through to its maximum breaking capacity.

Reliable Full-Range Electrical Protection
gG fuse links provide full-range protection by responding to both sustained overloads and high short-circuit currents. When an excessive current occurs, the calibrated fuse element interrupts the circuit before serious damage can be caused to cables, switchgear or connected industrial equipment.
The Mersen NH22GG50V250-1 is designed for installation by qualified professionals in compatible NH fuse bases and fuse switch-disconnectors. Its high breaking capacity, robust ceramic construction and clear double indicator make it suitable for critical industrial power systems where reliable overcurrent protection is essential.
Typical Applications
- Industrial power distribution boards.
- Electrical switchgear and fuse switch-disconnectors.
- Cable and feeder circuit protection.
- Manufacturing machinery and production equipment.
- Motor control centres and automation panels.
- Commercial and industrial electrical infrastructure.
