Direct start method for distribution box
A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a 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. DOL Starter Definition: A DOL starter (Direct On Line Starter) is a simple electrical device that starts a motor by applying full line voltage directly to its terminals. without using any special device for reducing the starting current. As the name implies, it switches the motor directly onto the three phase supply.
