Single phase dol starter wiring diagram. A single phase dol motor starter can be designed using the same components as shown in following diagram. 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.

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

And the normally open and normally close push button shown. This video covers the wiring diagram animation on direct online starter for single phase motor. 1 the following links are pre fitted to the starter. The l1 contactor is connected from normally open no to r phase using mccb.

The r y b is the three phase 380 volts supply. Despite this direct connection no harm is done to the motor. The wiring of direct on line control circuit starter is following. 13 17 with a flying lead to be connected to overload terminal 95.

Working principle of dol starter. In the above dol starter diagram. The contactor connection with thermal overload relay and the motor connection with overload relay is shown. 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.
