What is a kVA to Amps Calculator?
A kVA to Amps Calculator is a tool used to convert electrical power from kilovolt-amperes (kVA) to amperes (A). In electrical systems, kVA represents apparent power, which is the combination of real power (measured in kilowatts, kW) and reactive power (measured in kilovolt-amperes reactive, kVAR).
The apparent power (kVA) is a measure of the total power consumed or supplied by a circuit, taking into account both real and reactive components. The current (in amperes) flowing through the circuit depends on the apparent power and the voltage applied.
The kVA to Amps Calculator uses the following formulas to perform the conversion, depending on whether the system is single-phase or three-phase:
Single-phase kVA to Amps Calculation Formula:
I(A) = 1000 × S(kVA) / V(V)
Where:
- I(A) is the current in amperes (A).
- S(kVA) is the apparent power in kilovolt-amperes (kVA).
- V(V) is the voltage in volts (V).
Three-phase kVA to Amps Calculation Formula (Line to Line Voltage):
I(A) = 1000 × S(kVA) / (√3 × VL-L(V))
Where:
- I(A) is the current in amperes (A).
- S(kVA) is the apparent power in kilovolt-amperes (kVA).
- VL-L(V) is the line-to-line voltage in volts (V).
Three-phase kVA to Amps Calculation Formula (Line to Neutral Voltage):
I(A) = 1000 × S(kVA) / (3 × VL-N(V))
Where:
- I(A) is the current in amperes (A).
- S(kVA) is the apparent power in kilovolt-amperes (kVA).
- VL-N(V) is the line-to-neutral voltage in volts (V).
By entering the kVA value and the voltage value into the calculator, it calculates the corresponding current in amperes, helping engineers, electricians, and anyone working with electrical systems to determine the current load in the circuit and ensure that the current capacity of components (such as cables, transformers, and circuit breakers) is sufficient to handle the load safely.
How does this kVA to Amps Calculator work?
Let’s explain how the kVA to Amps Calculator works in a simple way so that everyone can understand the process.
The kVA to Amps Calculator is a handy tool designed to help you convert electrical power from kilovolt-amperes (kVA) to amperes (A). In electrical systems, kVA represents the total power consumed or supplied by a circuit, considering both the actual power used (kW) and the reactive power (kVAR).
To use this calculator, follow these steps:
- Choose the Phase: First, you need to select the phase of your electrical system. You can choose between “Single phase” and “Three phase.” This selection determines how the calculation will be done based on your electrical setup type.
- Enter the kVA Value: Enter the kilovolt-amps (kVA) value after selecting the phase. This represents the apparent power of your electrical system, which includes both real and reactive power components.
- Select Voltage Type (For Three Phase Only): If you chose “Three phase” in the first step, you can select the voltage type. You can choose “Line to line voltage” or “Line to neutral voltage.” This choice depends on your specific electrical setup.
- Enter the Voltage Value: Input your electrical system’s voltage value in volts (V). This is the voltage at which your devices or appliances are operating.
- Click Calculate: After providing the necessary information, click the “Calculate” button. The calculator will perform the conversion using the appropriate formula based on your phase and voltage type selections.
- Result in Amps: The calculator will display the amps (A) result. Considering the power and voltage you entered, this value represents the current flowing through your electrical system.
Remember, the purpose of this calculator is to help you understand the current load in your electrical circuit. It ensures that your electrical components, like cables, transformers, and circuit breakers, can handle the power requirements safely and efficiently.
Using the kVA to Amps Calculator, you can make informed decisions about electrical equipment and ensure a smooth and reliable electrical system operation.

Formulas of kVA to amps calculation with examples
Single-phase kVA to Amps Calculation Formula:
I(A) = 1000 × S(kVA) / V(V)
Example:
Apparent power (S) = 5 kVA
Voltage (V) = 220 V
I(A) = 1000 × 5 / 220
I(A) ≈ 22.73 Amperes (A)
Three-phase kVA to Amps Calculation Formula (Line to Line Voltage):
I(A) = 1000 × S(kVA) / (√3 × VL-L(V))
Example:
Apparent power (S) = 30 kVA
Line-to-Line Voltage (VL-L) = 400 V
I(A) = 1000 × 30 / (√3 × 400)
I(A) ≈ 27.39 Amperes (A)
Three-phase kVA to Amps Calculation Formula (Line to Neutral Voltage):
I(A) = 1000 × S(kVA) / (3 × VL-N(V))
Example:
Apparent power (S) = 50 kVA
Line-to-Neutral Voltage (VL-N) = 230 V
I(A) = 1000 × 50 / (3 × 230)
I(A) ≈ 90.41 Amperes (A)

How many amps is 25 kVA?
The formula is I(A) = 1000 × S(kVA) / V(V).
Let’s suppose the voltage is 240V.
So the calculation is:
I(A) = 1000 × 25 / 240
I(A) ≈ 104.17 Amperes (A)
So, with an ideal voltage of 240 V, 25 kVA is approximately equal to 104.17 amperes (A).
What is 75 kVA in amps?
Suppose the voltage is 240V.
So, the formula for the calculation is I(A) = 1000 × S(kVA) / V(V).
Where:
- S(kVA) is the apparent power in kilovolt-amperes (kVA), which is 75 kVA.
- V(V) is the voltage in volts, which is 240 V.
So, the calculation is:
I(A) = 1000 × 75 / 240 I(A) ≈ 312.5 Amperes (A)
So, with a voltage of 240 V, 75 kVA is approximately equal to 312.5 amperes (A).
