Mersen NH3GG50V450-1

The NH fuse-links system is categorized as a plug-in fuse system, comprising a fuse base which may include terminal covers and phase barriers, alongside a fuse-link equipped with blade contacts. It is crucial to note that the rated current non-interchangeability cannot be guaranteed, thus installation should be performed by qualified personnel. The gG type NH fuse-links are capable of handling a wide range of current surges, ensuring protection for cables and electrical equipment against short-circuit events.

These fuse-links can effectively interrupt currents from the lowest fusing level up to their maximum breaking capacity, thus providing reliable standalone protection. Additionally, they safeguard electrical devices and industrial configurations from the detrimental electrodynamic effects associated with high short-circuit currents. The NH fuse-links meet standards VDE 0636 Part 201 and IEC 60269-1 and -2, and feature a ceramic body, available in sizes 000, 00, 0, 1, 2, and 3. Their construction includes copper and silver-plated contacts, supporting an ampere range from 2 to 630 A, with a square body style.
