Why Choose the Mersen NH1GG40V160-1 NH Fuse Link?
The Mersen NH1GG40V160-1 is a high-performance NH1 gG fuse link designed to provide reliable overload and short-circuit protection for low-voltage electrical distribution systems. Manufactured to recognised DIN NH and IEC standards, it offers full-range protection for cables, conductors, switchgear and general-purpose industrial electrical equipment.
With a rated current of 160 A and an operating voltage of up to 400 V AC, the NH1GG40V160-1 is suitable for demanding industrial and commercial installations. Its high breaking capacity enables the fuse to interrupt substantial fault currents safely, helping protect electrical infrastructure and connected equipment from thermal and electrodynamic damage.
The fuse incorporates a robust ceramic body, silver-plated copper blade contacts and a double indicator for clear identification when the fuse has operated. Its isolated gripping lugs support safer handling with an approved NH fuse replacement device, while the standard NH1 format enables installation in compatible fuse bases and switch-fuse assemblies.

Reliable Protection for Low-Voltage Electrical Systems
Type gG fuse links provide full-range protection by safely interrupting both sustained overload currents and severe short-circuit currents. Their current-limiting performance helps reduce the thermal and mechanical stress applied to cables, switchgear, busbars and connected electrical equipment during a fault.
The Mersen NH1GG40V160-1 combines a high breaking capacity with low power dissipation and standardised NH blade contacts. This makes it a dependable protection solution for industrial distribution boards, commercial switchgear and machinery power circuits where reliable electrical safety is essential.
