STAR DELTA STARTER के लिए CONTACTOR SIZE SELECTION कैसे करते है?star delta starter

In this video we explain star delta starter contactor size selection
Basically when we run 3 phase motor with dol starter or reverse forward starter so we need to connect contactor according to full load current but in star delta starter we have three contactor
Main contactor
Star contactor
Delta contactor
So we don't need to connect contactor according to full load current
Basically star contactor should be 33℅of full load current
And main and delta contactor should be 58℅ of flc current
In this video explain all calculation according to 10 kw motor starter
