How Many Amps Is 230 kW at 575V?

230 kW at 575V draws about 271.69 amps on an AC three-phase circuit at PF 0.85, typical for commercial HVAC, industrial motors, rooftop units, and three-phase panel loads. Actual current varies with equipment power factor and duty cycle.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 230 ÷ 575 = 229,996 ÷ 575 = 399.99 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

229,996 ÷ (0.85 × 575) = 229,996 ÷ 488.75 = 470.58 A

AC Three Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (√3 × PF × V_L-L), where V_L-L is the line-to-line voltage

229,996 ÷ (1.732 × 0.85 × 575) = 229,996 ÷ 846.52 = 271.69 A

Equipment & Circuit Sizing

Breaker Sizing

Breaker ratings are in amps, not watts, so the real install answer depends on the equipment nameplate FLA, whether the load is continuous (NEC 210.19(A) sizes the conductor and OCP at 125% of a continuous load, equivalently 80% of breaker rating), conductor ampacity and temperature rating, ambient and bundling derates, and any motor or HVAC provisions (NEC 430 / 440). At roughly 271.69A on AC three-phase at 575V, the load sits in the bracket between a 300A standard size (non-continuous) and the next size up that covers a continuous load under 210.19(A) (around 350A). The actual install pick depends on whether the load is continuous and the factors above; a conversion page can't pick a single "right" breaker from the amp draw alone.

Energy Cost

230 kW costs $39.10/hour at $0.17/kWh (rates last reviewed April 2026). See breakdown.

Power Factor Reference (AC three-phase)

How the line current for 230 kW at 575V changes with load power factor, on the same AC three-phase circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

Load Type	PF	230 kW at 575V (AC three-phase)
Resistive (heaters, incandescent)	1	230.94 A
Fluorescent lamps	0.95	243.09 A
LED lighting	0.9	256.6 A
Synchronous motors	0.9	256.6 A
Typical mixed loads	0.85	271.69 A
Induction motors (full load)	0.8	288.67 A
Computers (without PFC)	0.65	355.29 A
Induction motors (no load)	0.35	659.82 A

AC Conversion Comparison

On DC, 230kW at 575V draws 399.99A. AC single-phase at PF 0.85 pulls 470.58A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 271.69A per line since the same 230kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	229,996 ÷ 575	399.99 A
AC Single Phase (PF 0.85)	229,996 ÷ (0.85 × 575)	470.58 A
AC Three Phase (PF 0.85)	229,996 ÷ (1.732 × 0.85 × 575)	271.69 A

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

How many amps is 230 kW at 575V?expand_more

230 kW at 575V draws about 271.69 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 399.99A on DC, 470.58A on AC single-phase.

What is the formula for kW to amps?expand_more

DC: Amps = (kW × 1000) ÷ Volts. AC single-phase: Amps = (kW × 1000) ÷ (Volts × PF). AC three-phase: Amps = (kW × 1000) ÷ (Volts_L-L × √3 × PF).

What size breaker would I need for 230 kW at 575V?expand_more

This is a sizing question, not a conversion question, and there is no single correct answer from a page like this. Breaker selection depends on the equipment nameplate FLA, whether the load is continuous (NEC 210.19(A) applies the 125% continuous-load rule), the conductor ampacity and temperature rating, any NEC 430/440 motor or HVAC provisions, and local code interpretation. Use the nameplate and a licensed electrician for the real install value; use this page only for the current-draw estimate that feeds into that process.

Is 230 kW single-phase or three-phase?expand_more

230 kW is typically three-phase in commercial and industrial settings.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 230 kW is easier to express than 229,996W. The math is identical, just scaled by 1000.
