Normaly relation between kVA and kW can be described as:
For 1phase system->kW=kVA X power factor.
For 3phase system->kW=3^(1/2)*V*I*power factor (V&I are
line voltage and current respectively)

During Starter Panel Com missing I Found The Main Incomer 40Amp MCB 10KA Trip When Motor Change Star To Delta Motor Rating 20HP BUT When We Use Same MCB To Other Motor It Does Not trip Or What Is Necessaries for Star Delta Starter MCB SFU MPCB OR MCCB And What are The Breaking Capacity of MCCB in the Motor above 15HP
