What is DOL Starter. A DOL starter (or Direct On Line starter or across the line starter) is a method of starting of a 3 phase induction motor.In DOL Starter an induction motor is connected directly across its 3-phase supply, and the DOL starter applies the full line voltage to the motor terminals. Despite this direct connection, no harm is done to the motor.

And one wiring is called controlling wiring. In the below dol starter wiring diagram, I shown a molded case circuit breaker, a magnetic contactor, Normally open push button, normally close push button switch, thermal overload relay, Motor trip indicator and 3 phase motor. In the above three phase dol starter wiring diagram.
