Answer Posted / irfan ahmad
V=440 V
P=30 Kw = 30000 w
we know that ,
P=1.732VI*(power factor)
I=30000/(1.732*440*0.9)
I=43.7 amps [power factor in application is 0.9]

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
