The NH fuse-link system is a plug-in type, comprising a fuse base that may include terminal covers and phase barriers, along with a fuse-link featuring blade contacts and a replacement device for HRC fuse pulling. This system, designated as aM, is characterized by partial-range breaking capacity and is specifically engineered to safeguard motor circuits due to its significant current-limiting properties and low power losses.

These fuse-links can interrupt currents ranging from 6.3 times the rated current up to their maximum breaking capacity, making them suitable exclusively for short-circuit protection. It is essential to pair them with additional switchgear to guard against overload conditions. Notably, these fuse-links can share the same rated current as the nominal current of the motors they protect.

The specifications include an amperage rating of 200 A and a rated voltage of 500 V as per IEC standards. The device features a power dissipation of 14.2 W at the rated current, ensuring reliable operation. The body is constructed from ceramic, while the connection terminals are made of silver-plated copper, enhancing conductivity. The fuse size is classified as NH1, with mounting via clip.
