Why Choose the Mersen NH1GG40V63 NH Fuse-Link?
The Mersen NH1GG40V63 is a high-performance NH1 gG fuse-link designed to provide full-range protection for cables, switchgear and electrical equipment in low-voltage power distribution systems. Manufactured to the DIN NH format, it offers reliable protection against both sustained overloads and high-level short-circuit faults.
Rated at 63 A and 400 V AC, the NH1GG40V63 is suitable for industrial, commercial and infrastructure electrical installations. Its gG operating characteristic allows it to interrupt currents across the complete operating range, from lower overload conditions through to severe short circuits.
The fuse-link features live gripping tags, silver-plated copper blade contacts, a robust ceramic body and a double visual indicator. Its 100 kA AC breaking capacity provides dependable fault interruption, while its standard NH1 construction allows installation in compatible NH fuse bases and fuse-switch disconnectors.
