Reliable Protection for Industrial Electrical Circuits
NH gG fuse-links provide full-range protection against both overload and short-circuit currents. When an excessive current occurs, the fuse element interrupts the circuit to help protect cables, conductors and connected electrical installations from damaging thermal and electrodynamic effects.
The Mersen NH3GG50V160-1 is designed for industrial low-voltage distribution systems where dependable fault interruption and straightforward fuse replacement are required. Its high breaking capacity makes it particularly suitable for switchboards, distribution panels, machinery and other installations with significant prospective fault currents.
Typical Applications
- Industrial low-voltage power distribution systems.
- Electrical switchboards and distribution panels.
- Cable and conductor overload protection.
- Short-circuit protection for electrical installations.
- Industrial machinery and control equipment.
- Commercial and industrial switchgear.
- Power distribution feeders and branch circuits.
