I think this is for 415V AC Supply, not for 380V AC.

Hi, if you will go to the online config. for motor feeder selection, it neither gives u option of 380Volts nor it will give you on 60Hz. I have calucalted the sizing of motor feeders as under:- 1) Motor Rating: 22KW 2) Voltage: 380V; Ferquency: 60Hz 3) Full load current: 46A 4) Inrush Current for DOL: 331.2A ( approx @ 7.2 times of rated current) ---------------------------------------------------------------- Contactor: 3RT1044 MPCB: 3RV13 41-4HC10 Relay: 3RU11 46-4HB0. This is as per TYPE 2 Co-ordination. Hope this will solve your problem |
