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.
