Star delta starter control wiring diagram pdf. In control wiring diagram all magnetic contactors coils are rated 220 vac. Refer to the below star delta circuit. In the above star delta starter control circuit wiring diagram with timer and normally close push buttonnormally open push button switch. 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.

Star delta connection circuit diagram. A star delta starter is a type of reduced voltage starter we use it to reduce the starting current of the motor without using any external device or apparatus. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly. The power circuit uses to create contact between the motor and three phase power supply.

This is a big advantage of a star delta starter as it typically has around 1 3 of the inrush current compared to a dol starter. So this time i want share my simple star delta circuit diagram completed with power and control line circuit i hope it can be as basic reference for all electrician about star delta starter diagram. This equipment appliance reduces starting current and starting torque. This type of starting is suitable for small motors below 5 hp 3 75 kw.
