## Abstract

A motor starter module is provided, the module according to the present disclosure including a PCB (Printed Circuit Board) substrate configured to communicate with and control the magnetic contactor, a mechanism part operating in association with an operation of the magnetic contactor, and an upper case covering the PCB substrate and an outer case of the mechanism part, whereby the magnetic contactor can be locally and directly driven, and controlled via communication to reduce a line cost, to shorten an operation time and to promote maximization of spatial utilization.

## Claims

### Claim 1

A motor starter module mounted at an upper surface of a magnetic contactor, the motor starter module comprising: a PCB (Printed Circuit Board) substrate configured to communicate with and control the magnetic contactor; a mechanism part operating in association with an operation of the magnetic contactor; and an upper case covering the PCB substrate and an outer case of the mechanism part.

### Claim 2 (depends on 1)

The motor starter module of claim 1, wherein the mechanism part includes a movable contact point unit physically interlocking with the operation of the magnetic contactor; and a fixed contact point unit transmitting an electric signal by physically connecting the PCB substrate and the magnetic contactor.

### Claim 3 (depends on 2)

The motor starter module of claim 2, further comprising: a movable contact point case fixing the movable contact point unit and physically connecting the motor starter module with the magnetic contactor; and a fixed contact point case fixing the fixed contact point and physically coupling the upper case.

### Claim 4 (depends on 3)

The motor starter module of claim 3, wherein the upper case includes at least one groove for coupling the fixed contact point case, wherein the fixed contact point case includes at least one hook part for physically coupling the upper case.

### Claim 5 (depends on 2)

The motor starter module of claim 2, wherein the movable contact point unit includes a movable contact point spring, a movable contact point arm, and a back spring, and the mechanism part operates in association with ON/OFF operation of the magnetic contactor by allowing the movable contact point arm to maintain contact with a 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.

### Claim 6 (depends on 2)

The motor starter module of claim 2, wherein the fixed contact point unit includes a fixed contact point arm and a screw, wherein the screw connects the fixed contact point arm with the PCB substrate via a wire, transmits an electric signal to the PCB substrate when ON/OFF operation of the magnetic contactor occurs, and wherein the PCB substrate controls the magnetic contactor based on the electric signal transmitted by the fixed contact point.
