PMAC811 intelligent motor protection controller is a new generation of enhanced
high-performance motor protection device which integrates motor protection, measurement, information management, communication and control functions. It is
suitable for three-phase AC asynchronous motor with rated voltage of AC380V or AC690V. He replaced the commonly used dispersed elements in the motor control center (MCC), greatly simplifying the control loop of the motor, improving the reliability and advancement of the motor control, and reducing the comprehensive application
cost.
