Why Choose the Mersen NH1GG69V160 NH Fuse-Link?
The Mersen NH1GG69V160 is a high-performance DIN NH gG fuse-link designed to protect cables, conductors and industrial electrical equipment against overloads and short circuits. Part of Mersen's established NH gG 690 V AC fuse-link range, it provides dependable full-range protection for low-voltage power distribution systems, switchgear and industrial control equipment.
Featuring a 160 A rated current and voltage ratings of up to 690 V AC and 400 V DC, the NH1GG69V160 uses a gG operating characteristic. This enables the fuse-link to interrupt fault currents ranging from lower overload currents through to severe short-circuit currents, allowing it to provide comprehensive circuit protection.
The fuse-link has an NH1 body size, a robust ceramic construction and live metal gripping lugs for handling with a suitable NH fuse replacement device. Its double indicator provides clear visual identification when the fuse has operated, helping maintenance personnel locate faults and complete replacement work efficiently.

Reliable Protection for Industrial Distribution Systems
gG fuse-links provide full-range protection by responding to both sustained overloads and high-level short-circuit currents. The Mersen NH1GG69V160 can therefore be used to protect cables, conductors, switchgear and connected electrical equipment throughout industrial power distribution installations.
During a severe electrical fault, the fuse-link interrupts the current rapidly to help limit thermal and electrodynamic stress on the installation. Its NH1 construction makes it suitable for use in compatible fuse bases, fuse-switch disconnectors and low-voltage switchgear assemblies.
Typical Applications
- Industrial low-voltage distribution systems.
- Electrical switchboards and switchgear assemblies.
- Cable and conductor protection.
- Fuse-switch disconnectors.
- Industrial control panels.
- Machinery and OEM electrical equipment.
