Formulas

DC: kW to Amps

I(A) = 1000 × P(kW) ÷ V(V)

1000 × 517.64 ÷ 575 = 517,641 ÷ 575 = 900.25 A

AC Single Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (PF × V(V))

517,641 ÷ (0.85 × 575) = 517,641 ÷ 488.75 = 1,059.11 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

517,641 ÷ (1.732 × 0.85 × 575) = 517,641 ÷ 846.52 = 611.48 A

AC Conversion Comparison

On DC, 517.64kW at 575V draws 900.25A. AC single-phase at PF 0.85 pulls 1,059.11A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 611.48A per line since the same 517.64kW is shared across three conductors instead of one.

Frequently Asked Questions

517.64 kW at 575V draws about 611.48 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 900.25A on DC, 1,059.11A on AC single-phase.
517.64 kW is typically three-phase in commercial and industrial settings.
517.64 kW equals 517,641 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 575V draws 611.48A per line versus 1,059.11A single-phase. Less current per conductor means smaller wire and lower I²R losses.
