Why Choose the Mersen NH000GG69V50 NH Fuse-Link?
The Mersen NH000GG69V50 is a compact and dependable DIN NH gG fuse-link designed to provide full-range protection against overload currents and short-circuit faults. As part of the established Mersen NH gG 690 V AC fuse-link range, it is suitable for protecting cables, conductors, switchgear and industrial electrical equipment.
This NH000 fuse-link combines a robust ceramic insulating body with double visual indicators and live gripping lugs. The indicators help maintenance personnel identify an operated fuse quickly, while its standard plain blade terminals enable installation in compatible DIN NH fuse bases and fuse-switch disconnectors.
With a rated current of 50 A, an AC voltage rating of 690 V and a DC voltage rating of 250 V, the NH000GG69V50 provides reliable general-purpose circuit protection. Its gG characteristic offers complete protection across the full operating range, from sustained overload currents to severe short-circuit faults.
Key Advantages
- Full-range gG protection against overloads and short circuits.
- 50 A rated current for industrial distribution circuits.
- 690 V AC and 250 V DC voltage ratings.
- 80 kA AC breaking capacity for reliable fault interruption.

Reliable Protection for Electrical Distribution Systems
The Mersen NH000GG69V50 provides complete protection across both overload and short-circuit operating regions. Its gG characteristic makes it suitable for protecting cables, conductors, distribution circuits and general-purpose electrical equipment without requiring a separate short-circuit protection fuse.
Its current-limiting construction restricts the peak current and energy passed during an electrical fault, helping reduce thermal and electrodynamic stress on switchgear and downstream components. The compact DIN NH000 format also enables integration into compatible industrial fuse bases and switch-disconnector assemblies.
Typical Applications
- Industrial power distribution systems.
- Low voltage switchboards and control panels.
- Cable and conductor protection.
- Commercial distribution equipment.
- OEM machinery and electrical assemblies.
- DIN NH fuse bases and fuse-switch disconnectors.
