Mersen NH0AM69V32

The NH fuse-link system serves as a plug-in fuse solution, comprising a fuse-base which may include terminal covers and phase barriers, along with a fuse-link featuring blade contacts and a replacement device (LV HRC fuse puller). Due to the design of this system, which does not ensure non-interchangeability of rated currents, it requires handling by qualified professionals.

Type aM NH fuse-links are classified as partial-range breaking capacity devices, specifically intended for motor circuit protection. These fuse-links are designed to be strongly current-limiting and exhibit low power losses, effectively interrupting currents from 6.3 times the nominal current (In) to their maximum breaking capacity, making them suitable exclusively for short-circuit protection. For protection against overloads, they must be used in conjunction with additional switchgear. It is noteworthy that the rated current of these fuse-links can match that of the motor's nominal current.
