A motor starter system and a method for operating same are disclosed. According to an embodiment of the present invention, reliability of a motor protection function during an overcurrent is improved by automatically controlling the on/off states of an electromagnetic contactor using an analog sensor value outputted from an external sensor. In addition, the present invention can receive an external sensor value through a connected upper monitoring device, monitor, in real time, the motor starter state, and transmit a control command for directly controlling the on/off states of the electromagnetic contactor, and thus enables excellent operation, integrated lifetime prediction, and motor load management. Furthermore, the present invention can reduce wiring work and a cost thereof and maximize the use of space more than when controlling the electromagnetic contactor by using the I/O of a PLC. |
