Reliable Protection for Industrial Electrical Circuits
The Mersen NH2GG69V40-1 uses a full-range gG fuse characteristic to protect cables, conductors and general-purpose electrical equipment. When excessive current flows through the fuse element, the fuse safely interrupts the circuit before damaging thermal and electrodynamic stresses can affect downstream components.
Its high voltage rating and breaking capacity make it suitable for industrial installations where substantial prospective fault currents may occur. The fuse link is designed for installation in compatible NH fuse bases and switch-fuse disconnectors and must be handled by qualified electrical personnel using suitable NH fuse replacement equipment.
Typical Applications
- Industrial low-voltage distribution boards.
- Electrical cable and conductor protection.
- Switch-fuse units and fuse-switch disconnectors.
- Industrial machinery supply circuits.
- Motor feeder and auxiliary power circuits.
- Manufacturing and process-control installations.
- Commercial power distribution systems.
- AC and DC equipment protection applications.
