Direct-On-Line (DOL) Starter Control Circuit Explanation: This diagram shows a Direct-On-Line starter wiring for a three-phase motor. The system includes a circuit breaker, contactor, overload relay, and push buttons for Start (green), Stop (red), and Trip (yellow) indicators. When the start button is pressed, the contactor energizes, supplying power to the motor. The overload relay protects the motor by tripping in case of overcurrent, while the stop button immediately cuts off the motor power.
