@izma.pakistan: #creatorsearchinsights Can you understand this Star-Delta starter wiring? A 3-phase 380V supply enters the Main Contactor. During starting, the Star Contactor connects the motor windings in Star to reduce starting current. After the motor accelerates, Star opens and the Delta Contactor closes for normal running. Question: Why can’t Star and Delta contactors be ON at the same time?
