This kVA to amps calculator converts apparent power in kVA to current in amps for single- and three-phase systems. Enter the kVA and voltage above to get the current instantly.
Formulas
Single phase: I = (kVA × 1000) ÷ V Three phase: I = (kVA × 1000) ÷ (√3 × VL)
Examples
- 10 kVA, 240 V single phase: I = 10,000 ÷ 240 = 41.7 A
- 10 kVA, 208 V three phase: I = 10,000 ÷ (√3 × 208) = 27.8 A

Frequently Asked Questions
How do I convert kVA to amps?
For single phase, amps equal kVA times 1000 divided by volts. For three phase, divide by the square root of 3 times the line voltage.
How many amps is a 10 kVA single-phase at 240V?
About 41.7 amps: 10,000 divided by 240.
Does power factor affect kVA to amps?
No. kVA is apparent power, so the conversion uses voltage only. Power factor matters when converting kW instead.
