Star/Wye Delta starters are use for motors with High Starting Currents and High starting torque, and motor with 6 Leads, for me I understand this way Any motor that uses over 50 full load amps needs a voltage reduction starter. This is a Basic Star/Wye - Delta system I designed for use with a Auto transformer. I didn't know much about it but as I went along doing it I figure it out. You'll need 3 contactors a Timer, Auxiliaries if really advanced, and The overload (which i left out). This video will help you to understand the Principle of the Timer because that what controls the whole circuit. Hope you understand.
