Motor Protection and Control Devices

DIN Rail-mounted Motor Protection and Control Device PMAC811 suitable for three-phase AC asynchronous motor with rated voltage of AC380V or AC690V.
DIN Rail-mounted Motor Protection and Control Device PMAC811 suitable for three-phase AC asynchronous motor with rated voltage of AC380V or AC690V.

DIN Rail-mounted Motor Protection and Control Device PMAC811 suitable for three-phase AC asynchronous motor with rated voltage of AC380V or AC690V.

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.
