Smart Motor Control and Protection Solution

Application

The motor is an important asset of the enterprise .It is necessary to monitor the running status and the efficiency of the motor, and protect the motor. ARD series smart motor protector is used for 660V low-voltage motor circuits with protection, measurement, control, communication, operation and maintance function,can realize multiple starting schemes to ensure the safe operation of the motor. It can be connected to the intelligent MCC or DCS production system. It is widely used in Chemical Industry、Power Plant、Pump Station、Mining Industry、Metallurgical Industry and so on.
