Formulas

DC: kW to Amps

I(A) = 1000 × P(kW) ÷ V(V)

1000 × 360.78 ÷ 400 = 360,784 ÷ 400 = 901.96 A

AC Single Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (PF × V(V))

360,784 ÷ (0.85 × 400) = 360,784 ÷ 340 = 1,061.13 A

AC Three Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (√3 × PF × VL-L), where VL-L is the line-to-line voltage

360,784 ÷ (1.732 × 0.85 × 400) = 360,784 ÷ 588.88 = 612.64 A

AC Conversion Comparison

On DC, 360.78kW at 400V draws 901.96A. AC single-phase at PF 0.85 pulls 1,061.13A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 612.64A per line since the same 360.78kW is shared across three conductors instead of one.

Same kW, Other Voltages

Each destination page leads with the interpretation most common for that voltage, so the amps shown below use the same basis as the page you'd land on: single-phase for residential voltages, three-phase for commercial/industrial panel voltages, DC for low-voltage.

Frequently Asked Questions

360.78 kW at 400V draws about 612.64 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 901.96A on DC, 1,061.13A on AC single-phase.
360.78 kW is typically three-phase in commercial and industrial settings.
360.78 kW equals 360,784 watts. Multiply kilowatts by 1000.
DC: Amps = (kW × 1000) ÷ Volts. AC single-phase: Amps = (kW × 1000) ÷ (Volts × PF). AC three-phase: Amps = (kW × 1000) ÷ (VoltsL-L × √3 × PF).
Three-phase at 400V draws 612.64A per line versus 1,061.13A single-phase. Less current per conductor means smaller wire and lower I²R losses.
