Three Phase Current Calculation

[creative_35]

I have a Motor written the following specifications:
voltage: 3phase 415v
connection: Star
Current:10Amp
Power/hp: 3.7kw/5

I want to know how much current it will draw on each phase( what rating circuit breaker I have to use for each phase)? Please answer.

Vline = ((3)^1/2)*Vphase

Iline = Iphase =10amps

each phase draws the same current according to the above relation. You have to use circuit breaker of rating 10amps.
