Why Choose the Mersen NH3GG50V355 NH Fuse-Link?
The Mersen NH3GG50V355 is a high-performance 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-grade construction and reliable current-limiting performance make it suitable for protecting cables, conductors, switchgear and power distribution equipment.
As part of Mersen's NH gG 500 V AC fuse-link range, the NH3GG50V355 combines a high breaking capacity with a double indication system for straightforward fault identification. The gG operating characteristic provides dependable protection throughout the fuse-link's complete operating range, helping reduce thermal and mechanical stress on downstream equipment during electrical faults.
Rated at 355 A, 500 V AC and 250 V DC, this NH3 fuse-link is suitable for demanding commercial and industrial power circuits. It incorporates live gripping lugs, plain blade terminals and a ceramic insulating body for installation in compatible NH3 fuse bases and fuse-switch disconnectors.

Reliable Protection for Low-Voltage Distribution Systems
gG fuse-links provide full-range protection for cables, conductors and general-purpose electrical circuits. During a severe fault, the fuse element rapidly interrupts the current and limits the amount of energy passed to downstream equipment, helping reduce damage to switchgear and connected components.
The Mersen NH3GG50V355 is designed for use by qualified electrical professionals in compatible NH equipment. Its double indicator helps maintenance teams locate operated fuse-links efficiently, while its standard NH blade construction supports integration into industrial fuse bases and switch-disconnector assemblies.
