Mersen NH0AM69V35

The NH fuse-link system is classified as a plug-in fuse system and comprises a fuse base, which may include terminal covers and phase barriers, along with a fuse-link featuring blade contacts and a replacement device for fuse-links (LV HRC fuse puller). Due to the design limitations concerning the interchangeability of rated current, installation should be conducted by qualified personnel.

These type aM NH fuse-links serve as partial-range breaking capacity devices, specifically intended for motor circuit protection. They effectively limit current and possess low power losses, interrupting currents ranging from 6.3 times the nominal current (In) up to their maximum breaking capacity. However, it is important to note that these fuse-links are intended solely for short-circuit protection and must be used alongside additional switchgear to safeguard against overload conditions. The rated current of these fuse-links can match the nominal current of the motor.
