Dol starter wiring diagram for three phase motor to wire a 3 phase motor the first thing to wire is a circuit breaker which is disconnect and connecting point then we will get the supply from circuit breaker and connect supply to contactor or starter and then to overload relay.

Three phase motor connection schematic power and control wiring installation diagrams. 13 17 with a flying lead to be connected to overload terminal 95. 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. Then read the below article and learn from simple dol starter wiring diagram.

The simplest form of motor starter for the induction motor is the direct on line starter. The contactor connection with thermal overload relay and the motor connection with overload relay is shown. 1 the following links are pre fitted to the starter. And the normally open and normally close push button shown.

In the above three phase dol starter wiring diagram. Wiring of the direct on line dol motor starter 1 three phase supply 230volt coil see wiring diagram. The coil of the contactor is 380 vac. All other control and power connections have to be made by the installer.

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. Despite this direct connection no harm is done to the motor. In the above dol starter diagram. 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.
