Why Choose the Mersen NH22GG50V80 NH Fuse-Link?
The Mersen NH22GG50V80 is a dependable DIN NH size 2 gG fuse-link designed to provide full-range protection for cables, conductors, electrical equipment and industrial low voltage distribution systems. With an 80 A rated current and a maximum rated voltage of 500 V AC, it is suitable for feeder circuits, switchboards and machinery installations requiring reliable overload and short-circuit protection.
Its gG operating characteristic enables the fuse-link to interrupt currents ranging from sustained overloads through to high prospective short-circuit currents. The current-limiting design helps reduce the thermal and electrodynamic stresses placed on downstream equipment during a fault, supporting safer and more dependable electrical installations.
The NH22GG50V80 features a robust ceramic body, standard blade contacts, live metal gripping lugs and a double indication system for convenient identification of an operated fuse-link. It is intended for installation in a compatible NH size 2 fuse base or fuse-switch disconnector and must be handled by suitably qualified electrical personnel.

Reliable Full-Range Circuit Protection
A gG fuse-link provides full-range protection, allowing it to respond to both prolonged overload conditions and severe short circuits. During a high-current fault, the fuse-link rapidly limits the peak current and let-through energy, helping protect cables, switchgear and connected equipment from excessive thermal and mechanical damage.
The Mersen NH22GG50V80 is suitable for coordinated protection within industrial and commercial distribution systems. Correct fuse selection must consider conductor capacity, load characteristics, system voltage, prospective fault current and coordination with other protective devices.
