DOL Starter (Direct Online Starter) is also knows as “across the line starter”. DOL starter is a device consist of main contactor, protective devices and overload relay which is used for motor starting operations. It is used for low rating usually below 5HP motors.In direct online starter method of motor starting, the motor stator windings is directly connected to the main supply where the DOL protect the motor circuit from high inrush current which may damage the overall circuit as the initial current is much more higher than the full rated current.
Protection Offered by DOL Starter:
The Motor starters not only provide the safe starting current but also provide protection to keep the motor safe during operation. It is clear that the DOL starter provides the full line voltage but it does provide the following protection:
