Motor Safety and Protection – NH2 aM 315A/690V Fuse Link

This fuse link, designed to protect motor circuits, is a key element ensuring reliable protection of electrical installations. Designed by ETI, it guarantees an effective response to overloads and short circuits, minimizing the risk of damage and downtime. The NH2 aM 315A/690V fuse link is ideal for both professional installers and end-users looking for a solid solution in terms of electrical safety.

Characteristics and Application

The NH2 aM 315A/690V fuse link with aM (motor) characteristic is specifically designed to protect electric motors from the effects of overloads and short circuits. The 'aM' characteristic means that the fuse link reacts with a delay to short-term current surges, typical of motor starting, while ensuring rapid intervention in the event of prolonged overloads or short circuits. The rated current of 315A at a voltage of 690V AC makes it suitable for use in demanding industrial environments.

Construction and Functionality

The fuse link is equipped with a combined (double) operating indicator, which allows for quick identification of the blown element. The construction of the fuse link ensures high reliability and durability, and the lack of metal insulated grips (IMGL) simplifies installation and replacement. It is important to remember that proper selection of the fuse link to the load is crucial to ensure optimal protection of the installation.
