A soft starter is an electronic device which regulates the voltage flowing to the motor at startup. By slowly ramping up the supply voltage to the motor, a smooth start without excessive current flow can be achieved. Soft starters are more expensive than DOL or star-delta, but they are widely used due to their convenience and simplicity.

The relay operates on the phase currents in Star-Delta starters. It should, therefore, be set at 0.6 times actual load current. A procedure similar to the one described for setting relays in DOL starters can be followed for Star-Delta starters. 2) Tripping of starters A starter may trip due to the following conditions;
STAR DELTA connection Diagram and Working principle. Descriptions: A Dual starter connects the motor terminals directly to the power supply.Hence, the motor is subjected to the full voltage of the power supply.Consequently, high starting current flows through the motor. This type of starting is suitable for small motors below 5 hp (3.75 kW).
What is DOL Starter. A DOL starter (or Direct On Line starter or across the line starter) is a method of starting of a 3 phase induction motor.In 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. Despite this direct connection, no harm is done to the motor.


At their simplest, DOL Starters act as a stop / start switch for a motor, but DOL starters are often fitted with overload protection devices to prevent short circuits or the motor overheating.
