Fuse link - NH1 aM 200A/690V - motor starter 004184417

Motor protection with NH1 aM 200A/690V fuse link

The NH1 aM 200A/690V fuse link is a reliable safety element for electrical circuits, primarily dedicated to motor protection. Designed by ETI, it meets the requirements of IEC 60269, guaranteeing effective protection against short circuits and overloads. Its 'aM' (motor) characteristic means it is specially adapted for use with inductive loads, such as electric motors – allowing for short-term current surges during start-up, while ensuring a quick response in the event of more serious failures.

Design and application

The NH1 fuse link is designed for operation in alternating current (AC) circuits. Its rated current of 200A and voltage of 690V make it suitable for use in industrial and commercial installations with higher power. Equipped with a combined operating indicator (double), it allows for quick identification of a blown fuse – which significantly facilitates diagnostics and repair of the installation. It is worth noting that the lack of metal isolated grips (IMGL) simplifies the installation and removal of the fuse link.

Advantages and benefits

• Specialization for motors: The aM characteristic provides optimal protection for electric motors, allowing for trouble-free start-up without unnecessary tripping of the fuse.

• Fast damage identification: The combined operating indicator facilitates the location of a blown fuse link, reducing installation downtime.

• Versatility: Designed for operation in AC circuits at 690V and 200A – it will find application in many different industrial installations.

• Safety: Provides effective protection against short circuits and overloads, minimizing the risk of equipment damage and fire.

• Simple installation: The lack of metal isolated grips facilitates installation and replacement of the fuse link.
