Why Choose the Mersen NH000GG40V40 NH Fuse-Link?
The Mersen NH000GG40V40 is a high-quality DIN NH size 000 gG fuse-link designed to provide reliable full-range protection for cables, conductors and electrical equipment in low voltage power distribution systems. Rated at 40 A with a maximum operating voltage of 400 V AC, it is ideal for industrial switchboards, machinery, motor control centres and commercial electrical installations.
Its gG utilisation category enables protection against both overload and short-circuit faults. The current-limiting design rapidly interrupts fault currents, reducing thermal and mechanical stress on connected equipment and helping improve the reliability of the electrical installation.
The NH000GG40V40 features a robust ceramic body, live gripping lugs and a double indication system, allowing fast identification of an operated fuse-link and safe replacement using an approved NH fuse puller. It is designed for installation in compatible NH000 fuse bases and fuse-switch disconnectors by qualified electrical personnel.
