The PST210-600-70 is a soft starter manufactured by ABB for motor control and protection in the industrial sector. It combines ABB’s extensive experience in industry applications with a deep understanding of specific application requirements, and uses advanced technology and design to provide smooth start and reliable operation of the motor.

PST210-600-70 soft starter uses three opposite parallel thyristors as voltage regulator, and uses this circuit structure, such as three-phase full control bridge rectifier circuit, to realize the smooth start of the motor. During the start-up process, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully switched on and the motor works at the mechanical characteristics of the rated voltage. This starting mode effectively reduces the starting current and avoids the starting overcurrent trip, thus protecting the motor and the power grid.

In addition, the PST210-600-70 soft starter has several advantages. First of all, its starting process is smooth and there is no impact torque, which reduces the wear of mechanical components and prolongs the service life of the motor. Secondly, the soft starter can adjust the size of the starting current according to the need to adapt to different loads and working conditions. Finally, PST210-600-70 soft starter also has the characteristics of high reliability, good stability, easy maintenance, etc., which makes it have a wide range of application prospects in industrial applications.

Overall, the PST210-600-70 soft starter is a high-performance, reliable and easy-to-use motor control product for a wide range of motor applications requiring smooth start and protection.
