Dol Starter Line Diagram. This is the simplest method of starting motors by connecting them directly to the supply. Direct on line semi automatic starting.
11 dol starter connection. The thermal overload is supplied as a separate item. Different starting methods are required just to start an induction motor as they draw more starting current.
And the normally open and normally close push button shown.
Direct on line motor starter dol is not suitable for. In the above dol starter diagram. Since the dol starter connects the motor directly to the main supply line the motor draws a very high inrush current compared to the full load current of the motor up to 5 8 times higher. The contactor connection with thermal overload relay and the motor connection with overload relay is shown.
