Dol electrical diagram. Thus there is no need to reduce the applied voltage to control the starting current. The starting current is not so very high and these motors can withstand starting current without any starters. Dol starter motor connection. The dol starter comprises of an mccb or circuit breaker contactor and an overload relay for protection. But if this motor is not a high power one it does not affect much. A direct online starter consits of two buttons a green button for starting and a red for stopping purpose of the motor.
Wiring diagram of dol starter. The circuit breaker is used for protection against short circuits while the overload relay protects the motor from overloading. In this article we will study about dol starter control diagram. Overloadindicator and power wiring diagram. The contactor is used for starting and stopping the motor where the green and red buttons are connected. In the above three phase dol starter wiring diagram.
In case of small rating motors having less than 05hp motors. The connection of contactor can be done among relay coil supply voltage as well as thermal overload. The l1 contactor is connected from normally open no to r phase using mccb. In order to avoid direct switching dol starters are implemented. During normal condition it acts as a switch. This may cause an electrical problem with the supply or it may cause a mechanical problem with the driven load.
The wiring diagram for a dol stater is shown below. A direct on line dol or across the line starter is an electrical device used to apply a full three phase line voltage to the electrical motor terminals.
