Three phase dol starter wiring diagram. Three phase dol starter wiring diagram. What is dol starter. A dol starter is a direct on line motor starter. The coil of the contactor is 380 vac. Sometimes known as an across the line starter this type of motor controller is used as a simple starter for larger electric motors providing. In the above dol starter diagram.
And if you want to learn it in image type diagram. The contactor connection with thermal overload relay and the motor connection with overload relay is shown. This is the wiring diagram of a dol starter. The wiring of direct on line control circuit starter is following. And one wiring is called controlling wiring. Despite this direct connection no harm is done to the motor.
All other control and power connections have to be made by the installer. The contactor has 3 types of contacts. The l1 contactor is connected from normally open no to r phase using mccb. Please see the attached diagram for guidance. The connection of contactor can be done among relay coil supply voltage as well as thermal overload. The r y and b phase are connected through mccb to the contactors.
The contactor has 3 main no contacts known as l1 l2 and l3. Three phase dol starter control and power wiring diagram reverse forward with limit switch reverse forward dol starter power and control wiring wiring of rev. Mccb or circuit breaker. 13 17 with a flying lead to be connected to overload terminal 95. A2 14 18. 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.
In the above three phase dol starter wiring diagram. Dol starter control diagram three phase. And the normally open and normally close push button shown. The ryb is the three phase 380 volts supply. The diagram below shows the wiring for a single phase motor and the path through the contactor and overload. 1 the following links are pre fitted to the starter.
This diagram illustrates possible wiring using a tesys d lc1d contactor and tesys lrd overload lrd and stop control is assumed to be by operation of the stop button on the overload. In the below diagram the mccb is not shown the three phase supply comes from mccb circuit breaker. In which the three phase induction motor connection shown and all the direct online starter wiring shown with simple steps. A dol starter or direct on line starter or across the line starter is a method of starting of a 3 phase induction motorin 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.
