Why Choose the Mersen NH1GG40V50 NH Fuse-Link?
The Mersen NH1GG40V50 is a reliable DIN NH gG fuse-link designed to provide full-range protection against overloads and short-circuit currents in low-voltage electrical distribution systems. Its industrial construction and dependable current-limiting performance make it suitable for protecting cables, conductors, switchgear and connected electrical equipment.
As part of Mersen's NH gG 400 V AC fuse-link range, the NH1GG40V50 offers a high breaking capacity and an integrated double indication system. During a fault, the fuse-link helps limit the electrical energy passed downstream, reducing thermal and mechanical stress on cables, busbars and switchgear while enabling maintenance personnel to identify an operated fuse quickly.
Rated at 50 A and 400 V AC, this NH1 fuse-link features live gripping lugs, plain blade terminals and a durable ceramic insulating body. It is designed for installation in compatible NH1 fuse bases and fuse-switch disconnectors within industrial, commercial and infrastructure power distribution systems.
