DOL starter (or Direct On Line starter or across the line starter) is a method of starting of an induction motor.
In DOL Starter an induction motor is connected directly across its 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.
A DOL motor starter contains protection devices, and in some cases, condition monitoring.
A direct on line starter can only be used if the high inrush current of the motor does not cause an excessive voltage drop in the supply circuit.
If a high voltage drop needs to be avoided, a star delta starter should be used instead.
Direct on line starters are commonly used to start small motors, especially 3 phase squirrel cage induction motors.
