CMC-LX series motor soft starter is a new type of motor starting and protection device that combines power electronic technology, microprocessor with automatic control. This type of soft starter can start or stop the motor smoothly without steps, avoid mechanical and electrical shocks caused by traditional staring methods such as direct star, △/Y start, self-coupling buck start, and effectively reduce the starting current and power distribution capacity, avoiding costs in expanding capacity. Besides, CMC-LX series motor soft starter has an internal integrated current transformer, so users do no need for external connection.

Motor power: 7.5-530kW
