The new generation of intelligent protector achieves computing power, accident analysis, motor fault report, etc. in addition to conventional low-voltage motor protection, monitoring and control function.As a comprehensive measurement, the motor protection control system can improve the reliability and security of the power supply system of the enterprise, improve automation management level of the enterprise in the operation of the production.LCD full screen display can show the following date in Chinese: operation process, three-phase voltage, three-phase current, power factor, time/total power, frequency, power, apparent power, fault information and report to the police action value, time/total running time, field bus communication, and other functions, to realize the remote automatic control of the motor, the scene to direct control, terminal control, positive &negative start control, tri-star start control,the lotus root step-down start control, direct bypass start control mode. Fieldbus RS5485 interface supports a variety of communication protocol, can be used for a variety of computer industrial control configuration software to realize the network communication management, can also be connected to DCS system through the electrorheological 4-20mA signal output, to send out the motor running parameters output, constitute a distributed integrated power monitoring and control system, achieving control, remote measurement, remote communication, remote control, protection, setting.With software, hardware and electromagnetic compatibility auto-calibration function design, the product has strong anti-interference ability and precise sensitive action reliability, small volume, compact structure, convenient installation, can be installed directly or by guide screw installation in the low voltage control terminal cabinets as well as 1/4 and above all sorts of drawer, particularly suitable for scientific and effective field using for industrial-grade protection, measurement and control unit.

| Overload control protection | When the motor overload carrying, control protection device track and calculate overload current according to the heat capacity (Q) of the motor thermal. In thermal overload protection fully considered in the calculation of the motor stator and rotor temperature rise, meanwhile considering the unbalanced three-phase affect motor heating. When the current increases to control protection value, giving alarm prompt action to trip value time. | |
| Underload (flow) protection | when protected current through less than the setting value, action set alarm, and give the alarm or stop work. | |
| Motor Shaft Lock Protection | To prevent the occurrence of severe motor running blockage or motor overload operation while the multiple of current reach setting current, give signal alarm or stop | |
| Unbalance protection of three-phase current | Through three phase current or three-phase voltage according to the ratio of the minimum line current and maximum line current alarms when the set values for the reach or exceed hint to trip condition | |
| Open-phase protection | When any phase in three phase current in the current ratio is greater than the imbalance Angle value is defined as the phase failure fault | |
| Over voltage protection | Monitor three-phase voltage values, any phase voltage higher than the set value alarm prompt in action time | |
| Low voltage protection | Monitor three-phase voltage values, any phase voltage lower than the set value alarm prompt in action time | |
| ground protection | Through external zero sequence current transformer measurement, according to the current of motor phase the conductor (PE) or (PEN) whether to start the leakage fault protection function, when greater than the setting values of the leakage protection device, protective device sends an alarm to trip time | |
| Anti-interference protection | monitor continuously the voltage of the equipment, when the system voltage instantaneous fall then recover, motor can restart | |
| Start timeout protection | Continuously monitor the starting current delay time, when the current is greater than the delay time to complete the boot device, three phase current was 1.2 times greater than the set current start timeout tripping protection action | |
| Reverse protection | When detect three-phase voltage phase sequence is not correct, stop and can not start the motor | |
| External fault protection | When check the external switch input signal and the default state of switch input is inconsistent, the device can not start | |
