| 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 heatin. 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 | ||||

| 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 | ||||
