The features of technology

     The main function

1.Current display: it can display three-phase average current and A, B, C three-phase current.

2.       Overload protection: when overload, the relay will release, and cut off the motor’s power supply. There are definite time lag and inverse time lag two action ways. Definite time can be adjusted, providing five inverse time lag curved shape.

3.       Phase-lacking protection: when you test phase loss, cut off the motors’ power supply, action time can be adjusted.

4.       Three-phase unbalance protection: when you test three-phase current unbalance, you should cut off the motors’ power supply, the unbalance action point and spacing interval can be set.

5.       Self recovery function: cut off the motors’ power supply because of faults, it can recover by itself some times, the times and spacing interval can be set.

6.  The function of lock faulty current: cut off the motors’ power supply because of faults occur, it can lock and display the current at faults occur moment.

7.  The function of time relay: as an additional function, its internal integrates a time relay
