Fuse link - NH0 aM 160A/690V - motor starter 004112136

Installation and motor safety – NH0 aM 160A/690V fuse link

This NH0 aM 690V fuse link with a rated current of 160A is a key element in protecting electrical installations, especially those powering motors. Designed by ETI Polam, it provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage and downtime. Its construction and characteristics make it a reliable component in energy distribution systems.

Characteristics and application

The NH0 aM fuse link from the WT-NH series is a component designed to protect electrical circuits against the effects of overloads and short circuits. The designation "aM" indicates its specialization – motor protection. Thanks to this characteristic, the fuse link allows for short-term overcurrents during motor starting without unnecessarily disconnecting the circuit. This is particularly important in industrial and workshop applications where motors are frequently started and stopped. The rated voltage of 690V makes it suitable for use in medium-voltage networks. The top indicator facilitates visual control of the fuse link status – whether it has operated and needs to be replaced.

Advantages for the installer and user

• Motor protection: The aM characteristic provides optimal protection for electric motors against overloads and short circuits, which translates to a longer lifespan of devices and reduced repair costs.
• Fast fault identification: The top indicator allows for easy and quick checking of the fuse link status after operation, which facilitates diagnosis of problems in the installation.
• Safety: Provides effective protection of the electrical installation and connected devices against the effects of failures.
• Compliance with standards: The fuse link meets the requirements of IEC 60269 standard, which guarantees its quality and reliability.
• Simple installation: The standard NH0 size facilitates the replacement of used fuse links without the need to modify the existing installation.
• Durability: Solid construction ensures long-lasting and reliable operation even in harsh operating conditions.
• Rated current 160A: Suitable for a wide range of industrial and commercial applications requiring protection with such a current intensity.
• Rated voltage 690V: Enables use in medium-voltage networks, increasing the range of applications.

It is worth remembering that the lack of metallic insulated grips (IMGL) means that appropriate caution must be exercised during installation and replacement of the fuse link – appropriate insulation of tools must be ensured and the circuit power supply must be disconnected.
