Accepted Answer

A DOL starter circuit diagram is used to control the starting and stopping of an electric motor.

DOL stands for Direct-On-Line.
The circuit consists of a contactor, overload relay, and start and stop buttons.
When the start button is pressed, the contactor closes and power is supplied directly to the motor.
The overload relay protects the motor from excessive current.
The stop button opens the contactor and stops the motor.

DOL Starter for Motors – Direct Online Starter Diagram, Working, Types & Applications
The induction motor draws a huge amount of current at startup. This starting current can damage the motor windings. In order to avoid any damage, we use different techniques to reduce the starting current using Motor Starter (e.g. star delta or DOL starters). These techniques depend on the motor ratings and the load connected to the motor. Apart from this, the motor starter also protects the motor from overloading and overcurrent.

The Direct Online or DOL starter employs full voltage or across the line starting technique where the motor is directly connected to full voltage through MCCB or circuit breaker and relays for overload protection. This is why such a starter is used with induction motors rated below 5 hp.
