There are two types of circuits in the dol starter diagram given above. Direct on line starter wiring diagram.
Dol Starter Control Diagram Engineering Portal
Dol control circuit diagram. Three phase dol starter wiring diagram for 3 phase motor. And nc off switch and no on switch. Dol starter control diagram three phase. Wiring diagram of dol starter. It is powered by only 2 phases of the power supply and it is responsible for starting and stopping the power supplied to the motor. The control circuit and the power circuit.
The control circuit. The l1 contactor is connected from normally open no to r phase using mccb. The wiring of direct on line control circuit starter is following. The contact are connected directly in the control circuit of dol to switch on km1 contactor. In this post we are going to know the details of each part of dol starter diagramall parts of the dol starter power circuit diagram and control circuit diagram are explaineddirect online starter or dol starter is very useful and commonly used ac starterdol starters are mainly used with up to 5 hp motors. The connection of contactor can be done among relay coil supply voltage as well as thermal overload.
In the diagram you will see the three pole mccb circuit breaker molded case circuit breaker a magnetic contactor a motor over current thermal overload protection relay. How dol starter control diagram works when we press the start button to start the motor the relay gets the phase and circuit completed thus coil energizes and contactors produce magnetic field the main contactor closes and motor gets the supply and the motor startswhen we press the stop button the circuit will interrupt and the motor stop. In three phase dol starter wiring the two types of wiring done. Can you please explain this phenomenon or the reasoning of this problem.
