Why Choose the Mersen NH3GG50V200 NH Fuse Link?
The Mersen NH3GG50V200 is a robust NH3 size gG fuse link designed to provide full-range protection for low-voltage electrical cables, switchgear and industrial power distribution systems. With a rated current of 200 A and a voltage rating of 500 V AC, this high rupturing capacity fuse delivers dependable protection against overloads and short-circuit faults in demanding industrial environments.
Its gG operating characteristic provides complete cable and equipment protection across its full operating range. The fuse link safely interrupts sustained overload currents and severe short-circuit faults, helping to minimise damage to electrical equipment, conductors and distribution systems.
The NH3GG50V200 features a durable ceramic body, silver-plated blade contacts and live gripping tags for installation and replacement using a compatible NH fuse puller. A built-in double indicator clearly shows when the fuse has operated, allowing maintenance engineers to identify faults quickly and reduce downtime.
