Three Phase Contactor Circuit Diagram. These motors are connected directly to either a 3 phase switch or a contactor as a method of control. 19 less than a minute.
Disconnect these three power wires at the load using a screwdriver or socket wrench. 3 phase direct on line motors consist of three sets of windings one for each phase connected in delta. This directs the current through from l2 and directs it through the 3 rd phase on the contactor and overload l3 t3.
We connect the circuit breaker contactor and overload relay in series between electrical supply and motor as shown in the below diagram.
