Reliable Protection for Industrial Power Distribution
gG fuse-links provide full-range protection by interrupting both sustained overload currents and high short-circuit currents. This allows the NH0GG69V80 to be used as a standalone protective device for suitable cables, feeders and electrical equipment within low-voltage power distribution systems.
The fuse-link’s high breaking capacity and current-limiting performance help reduce the thermal and electrodynamic effects of severe electrical faults. Installation and replacement should be carried out by a qualified electrical professional using an appropriate NH fuse replacement device.
Typical Applications
- Industrial switchboards and distribution panels.
- Cable, feeder and line protection.
- Motor control centres and machinery panels.
- Commercial low-voltage distribution systems.
- Manufacturing and process installations.
- Industrial electrical equipment and automation systems.
