In control wiring diagram all magnetic contactors coils are rated 220 vac. Normally it gets one phase constant from incoming supply voltage a1 when coil gets second phase relay coil energizes and magnet of contactor produce electromagnetic field and due to this plunger. Single phase dol starter wiring diagram. 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.
We have to use all 3 poles of the overload relay otherwise the imbalance due to the current flow in only 2 of them will cause unnecessary tripping.
