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.
It can measure and display electrical parameters such as voltage, current, power, energy, and support RS485 communication and electric energy pulse output.
Monitoring electrical parameters such as voltage, current, power, frequency, harmonics and three-phase imbalance, cable and bus temperature.
1）Protection function
| Start timeout | External Fault | tE time |
| Overload | Insulation Fault | tE time |
| Underload | OverVoltage | Loss of pressure (anti-shake) |
| Short circuit | OverVoltage | 4-20mA input protection |
| Blocking | Phase Failure | Ground |
| Stall Phase | Sequence | Leakage |
| Unbalance | OverPower |
2）Communication
