Dol starter remote control 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. In this article we will discuss dol starter direct online starter working principle and construction dol starter diagram control diagram power circuit and wiring single 3 phase starter direct on line is the simplest and cheapest method used for starting three phase motor. 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.
Despite this direct connection no harm is done to the motor. 1 the following links are pre fitted to the starter. I checked continuity to l l l body its ok but when i started the motor in fraction of seconds the relay fused out what the reason i cant find it please tell me and suggestion me. A2 14 18.
