I = kW × 1,000 ÷ (V × PF)Within this model
Electrical input power only. AC is sinusoidal steady-state. For three-phase, enter total power and line-to-line RMS voltage; the load must be balanced. AC uses true power factor. This does not select cable, breaker or supply capacity.
What the numbers mean.
A kilowatt is 1,000 watts. The supply type changes the power-current relationship, so select it explicitly. Current calculated here describes the entered operating conditions, without any allowance for starting behaviour or a changing load.
Formula reference: Schneider Electric · Electrical Installation Guide ↗A worked example
2.3 kW × 1,000 ÷ (230 V × 1) = 10 A for single-phase AC.
