Dol starter direct online starter is also knows as across the line starter. Direct on line starter is the simplest kind of starter that connects the motor directly to the power supply through a three phase contactor. In order to avoid direct switching dol starters are implemented.
Calculate size of each part of dol motor starter for the system voltage 415v 5hp three phase house hold application induction motor code a motor efficiency 80 motor rpm 750 power factor 0 8 and overload relay of starter is put before motor.
Hence such a starter cannot reduce the starting inrush current. Dol starter is a device consist of main contactor protective devices and overload relay which is used for motor starting operations. Dol starter consists of mccb contactor and overload relay. The dol starter consists of two switches namely green and red where the green switch is used to start and red switch is used to stop the motor.
