Beautiful Dol Control Circuit Diagram
Direct on line starter wiring diagram.
Dol control circuit diagram. Wiring diagram of dol starter. Normally it gets one phase constant from incoming supply voltage a1 when coil gets second phase relay coil energizes and magnet of contactor produce electromagnetic field and due to this plunger of contactor will move and main contactor of. Dol starter control circuit diagram consist components like main power contactor start button stop push button and overload relay is connected in series this circuit is called control circuit of dol motor starter.
Working principle of dol starter. All controlling of starter are controlled by this circuit. A direct online starter consists of two buttons a green button for starting and a red for stopping purpose of the motor.
The all main operations are done in the control circuit. The control circuit and the power circuit. There are two types of circuits in the dol starter diagram given above.
When the coil of the contactor is energized then the contactor closes the power circuit and the motor gets the power supply. The dol starter comprises an mccb or circuit breaker contactor and an overload relay for protection. The main heart of dol starter is relay coil.
The control circuit is connected to the contactor coil. Dol starter wiring diagram the wiring diagram for a dol stater is shown below.
