Abstract:
1. A motor starter module mounted on an upper surface of a magnetic contactor, the motor starter module comprising: a Printed Circuit Board (PCB) substrate configured to communicate with and control the magnetic contactor; a mechanism part operating according to an ON/OFF state of the magnetic contactor and physically connecting the PCB substrate to the magnetic contactor; and an upper case covering the PCB substrate and an outer case of the mechanism part, wherein the mechanism part includes: a movable contact point unit fixed in a movable contact point case and moving according to the ON/OFF state of the magnetic contactor, the movable contact point unit including a movable contact point arm, a movable contact point spring and a back spring; and a fixed contact point unit fixed in a fixed contact point case, physically connecting the PCB substrate to the magnetic contactor and transmitting an electric signal to the PCB substrate according to whether the fixed contact point unit is in contact with the movable contact point unit, the fixed contact point unit including a fixed contact point arm, wherein the mechanism part causes the movable contact point arm to contact the fixed contact point arm due to a load of the movable contact point spring and the back spring when the magnetic contactor is in the OFF state and causes the movable contact point arm to not contact the fixed contact point arm by distancing the movable contact point arm from the fixed contact point arm due to downward movement of the movable contact point unit when the magnetic contactor is in the ON state.
