A motor starter module mounted at an upper surface of a magnetic contactor, the motor starter module comprises a PCB substrate configured to communicate with and control the magnetic contactor; a mechanism part operating in association with an operation of the magnetic contactor controlled by an electric signal of the PCB substrate; and an upper case covering the PCB substrate and an outer case of the mechanism part, characterized in that the mechanism part includes: a movable contact point unit including a movable contact point arm, a movable contact point spring, and a back spring, and is configured to physically interlock with the operation of the magnetic contactor; and a fixed contact point unit including a fixed contact point arm and a screw, and is configured to transmit the electric signal by physically connecting the PCB substrate and the magnetic contactor, wherein the mechanism part is configured to operate in association with ON/OFF operation of the magnetic contactor by allowing the movable contact point arm to maintain contact with the fixed contact point arm when the magnetic contactor is in an OFF state, and by allowing the movable contact point arm to lose contact with the fixed contact point arm when the magnetic contactor is in an ON state. a PCB substrate configured to communicate with and control the magnetic contactor; a mechanism part operating in association with an operation of the magnetic contactor controlled by an electric signal of the PCB substrate; and an upper case covering the PCB substrate and an outer case of the mechanism part, characterized in that the mechanism part includes: a movable contact point unit including a movable contact point arm, a movable contact point spring, and a back spring, and is configured to physically interlock with the operation of the magnetic contactor; and a fixed contact point unit including a fixed contact point arm and a screw, and is configured to transmit the electric signal by physically connecting the PCB substrate and the magnetic contactor, wherein the mechanism part is configured to operate in association with ON/OFF operation of the magnetic contactor by allowing the movable contact point arm to maintain contact with the fixed contact point arm when the magnetic contactor is in an OFF state, and by allowing the movable contact point arm to lose contact with the fixed contact point arm when the magnetic contactor is in an ON state. a movable contact point unit including a movable contact point arm, a movable contact point spring, and a back spring, and is configured to physically interlock with the operation of the magnetic contactor; and a fixed contact point unit including a fixed contact point arm and a screw, and is configured to transmit the electric signal by physically connecting the PCB substrate and the magnetic contactor, wherein the mechanism part is configured to operate in association with ON/OFF operation of the magnetic contactor by allowing the movable contact point arm to maintain contact with the fixed contact point arm when the magnetic contactor is in an OFF state, and by allowing the movable contact point arm to lose contact with the fixed contact point arm when the magnetic contactor is in an ON state.
