Mersen F223703

The NH fuse-link system is categorized as a plug-in fuse system, consisting of a fuse-base, which may include terminal covers and phase barriers, along with a fuse-link equipped with blade contacts and a replacement device (LV HRC fuse puller). Due to the system's design, which does not ensure non-interchangeability of rated currents, it must be managed by qualified personnel.

The type 'gG' NH fuse-links are characterized by their full range breaking capacity, providing essential protection for cables and equipment. They are capable of interrupting current surges from the lowest fusing current up to their rated breaking capacity, and can function independently as protective devices. Furthermore, they safeguard electrical apparatus and industrial installations against the electrodynamic impacts of extremely high short-circuit currents. Rated Power Dissipation values for these Mersen NH fuse-links at 400VAC are maintained below the maximum limits set by the IEC 60269 standard.
