Why Choose the Mersen NH0GG69V80 NH Fuse-Link?
The Mersen NH0GG69V80 is a high-performance DIN NH gG fuse-link designed to provide full-range protection for low-voltage electrical distribution systems, industrial switchgear and power equipment. Manufactured by Mersen, this NH size 0 fuse-link protects cables, feeders and electrical installations against overloads and short circuits, helping minimise equipment damage and unplanned downtime.
As part of the proven Mersen NH gG 690 V fuse-link series, the NH0GG69V80 features a durable ceramic body, silver-plated copper blade contacts, live gripping lugs and a double indication system. Its standardised DIN NH format enables straightforward installation in compatible fuse bases within switchboards, distribution panels and industrial control systems.
With a rated current of 80 A, a rated voltage of 690 V AC, a 400 V DC rating and an 80 kA AC breaking capacity, the NH0GG69V80 provides dependable protection for demanding industrial and commercial power distribution applications.

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.
