Type gg NH fuse-links are full range breaking capacity fuse-links and are used to protect cables and equipment. They can interrupt any current surge, from the lowest fusing current up to their breaking capacity, and so can be used alone as protection. They also protect electrical devices and industrial set-ups from the electrodynamic effects of very high short-circuit currents. Rated Power Dissipation values of Mersen NH fuse-links 4VAC are below the maximum values required by standard IEC 6269.
