Wiring Diagram Three Phase Contactor. The three phase supply shown in the diagram L1 L2 L3 which is connected to the MCCB circuit breaker and after that the supply goes to the magnetic contactor and from the contactor the supply goes to the thermal overload relay and from the thermal overload relay the supply. This panel has a three phase main breaker or sometimes it.
When you press the start button and the stop button is not pressed the 24VDC relay energizes and it pulls in the R1 contactor that feeds three phase power to the motor. The three phase supply shown in the diagram L1 L2 L3 which is connected to the MCCB circuit breaker and after that the supply goes to the magnetic contactor and from the contactor the supply goes to the thermal overload relay and from the thermal overload relay the supply. We have actually gathered several pictures ideally this picture works for you and assist you in.
When the motors switch is turned on voltage flows through the contactors coil creating a magnetic field.
