kVA to Amps Calculator – AC Single Phase & Three Phase
Easily convert kilovolt-amps (kVA) to amps (A) for AC single phase and AC three phase circuits. Enter the apparent power in kVA and voltage to get the current in amps instantly.
kVA to Amps Formula
- AC Single Phase: I (A) = S (kVA) × 1000 ÷ V (V)
- AC Three Phase (Line-to-Line): I (A) = S (kVA) × 1000 ÷ (√3 × V (V))
Example Calculations
- AC 1-Phase: 2.3kVA, 230V → 2.3 × 1000 ÷ 230 = 10A
- AC 3-Phase: 13.856kVA, 400V → 13.856 × 1000 ÷ (1.732 × 400) = 20A
