NH fuse-links aM 690VAC , double indicator/live gripping-lugs size 000, 00, 0, 1, 2, 3
The NH system is classified among plug-in fuse systems and is composed of: * fuse-base (possibly including terminal covers and phase barriers) * fuse-link with blade contact * fuse-link replacement device (LV HRC fuse puller) Since the design of this system cannot guarantee non-interchangeability of rated current it must be handled by a qualified professional.
Type "aM" NH fuse-links are partial-range breaking capacity fuse-links, used to protect motor circuits as they are strongly current-limiting and have low power losses. They interrupt currents from 6.3 times In up to their maximum breaking capacity and are therefore suited for short-circuit protection only. They must be associated with other switchgear for protection against overloads. These fuse-links can have a rated current equal to the motor's nominal current.
