Contactor Wiring Diagram 3 Phase. Dol starter wiring diagram for three phase motor. We connect the circuit breaker contactor and overload relay in series between electrical supply and motor as shown in the below diagram.
In the industrial system we use mostly three phases of electric power for electric induction motors. It reveals the parts of the circuit as simplified forms as well as the power as well as signal connections in between the tools. Dol starter wiring diagram for three phase motor.

Take additional black red and blue three phase wire that is the same size as the supply wires and connect one end of these wires to the t1 t2 and t3 terminals on the contactor. T1 t2 and t3 represent the load side of the contactor. To wire a 3 phase motor the first thing to wire is a circuit breaker which is a disconnect and connecting point then we will get the supply from the circuit breaker and connect the supply to the contactor or starter and then to the overload relay.
