kVA to Amps Calculator

Updated Amps to kVA

You can convert kVA to amps (A) by providing the power in kVA and voltage values below. If needed, you can also calculate for a three-phase electrical circuit by selecting the appropriate phase.

Note: power factor = 1

Single Phase kVA to Amps Calculation Formula

I(A) = 1000 × S(kVA)V(V)

S(kVA) – Apparent power in kVA.

V(V) – Voltage in volts.

For example, let’s find the current for a 230-volt circuit with 20 kVA of apparent power.

I(A) = 20 kVA × 1,000/230 V = 86.9565 A

3 Phase kVA to Amps Calculation Formula

Calculation with Line-to-Line Voltage

I(A) = 1000 × S(kVA)√3 × VL-L(V)

VL-L(V) – Line-to-Line voltage in volts;

S(kVA) – Apparent power in kVA.

For example, let’s find the current for a 400-volt three-phase circuit with 25 kVA of apparent power.

I(A) = 25 kVA × 1,000/1.732 × 400 V = 36.0854 A

Calculation with Line to Neutral Voltage

I(A) = 1000 × S(kVA)3 × VL-N(V)
