Reliable Protection for Industrial Electrical Circuits
NH gG fuse-links provide full-range protection against both overload and short-circuit currents. When excessive current flows, the fuse element interrupts the circuit to help protect cables, electrical equipment and industrial installations from damaging thermal and electrodynamic effects.
The Mersen NH3GG50V224-1 is designed for industrial low-voltage distribution systems where dependable fault interruption is required. Its gG characteristic allows the fuse-link to operate across the full overcurrent range, while its high AC breaking capacity makes it suitable for switchboards, distribution equipment and industrial systems with substantial 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 production equipment.
- Commercial and industrial switchgear.
- Power distribution feeders and branch circuits.
