| Overload control protection | when the motor is overload,the over current will be calculated according to the motor heat capacity tracking.Fully considered the motor rotor and stator's temperature rise and the influence to the motor heating because of the three-se unbalance.When the current reached the control protection value,the device will do the alarming and notice the shutdown delay time. | |
| Underload protection | when any one of the three-se current is lower than the set underload value,the device will do the alarming and notice the shutdown delay time. | |
| Locked-rotor protection | when the current value reached the set current multiples,the protection device will do the alarming and notice the shutdown delay time. | |
| Three-se current unbalance protection | when the ratio of the minimum se or the maximum ent reaches or exceeds the set value, the protection device will do the alarming and notice the shutdown delay time. | |
| Open-se protection | It will be judged as open-se fault if any one of the three-se current's ratio is not bigger than the unbalanced angle value, the device will do the alarming and notice the shutdown delay time. | |
| Overvoltage protection | The protection device and the measure device monitor the three-se voltage value, the device will do the alarming and notice the shutdown delay time if the equipment's largest voltage is higher than the set value. | |
| Undervoltage protection | The protection device and the measure device monitor the three-se voltage value, the device will do the alarming and notice the shutdown delay time if the equipment's smallest voltage is lower than the set value. | |
| Leakage (earth)protection | Judge the leakage fault by using the zero sequence current transformer to measure the protective conductor(PE)or (PEN)'s short-circuit leakage current value.When the short-circuit leakage current value is bigger than the set leakage value, the device will do the alarming and notice the shutdown delay time. | |
| Electric shock protection | The protection device monitors the equipment's voltage continuously,when the system voltage recovered after the moment dropped,the motor can start again. | |
| Timeout protection | The protection device inspects the start-up current delay time,when the equipment can bot be started up within the start-up delay time,and the three -se current is 1.2 time bigger than set current,the timeout protection will function and the power will turn off. | |
| Reversal protection | When the protection device monitored the three-se voltage sequence is not correct,the equipment can not start-up. | |
