Three-phase Current

Current per phase for a three-phase load.

Power(kW)

Line voltage(V)

Power factor

Current per phase

17.6 A

Apparent power12.22 kVA

Formula

I = (P x 1000) / (sqrt(3) x V x power factor)

(11 x 1000) / (1.732 x 400 x 0.9) = 17.6 A

Three phase, line voltage. Size the circuit and protection per AS/NZS 3000. Guide only.
