How to Convert kVA to Amps Step by Step
Follow these steps.
kVA measures apparent power. Amps measure current. To convert kVA to amps, you divide the kVA value (in watts) by the system voltage.
kVA to Amps Formula (Three-Phase)
For a three-phase system:
Amps = (kVA × 1000) ÷ (√3 × Volts)
Here, √3 = 1.732.
kVA to Amps Formula (Single-Phase)
For a single-phase system:
Amps = (kVA × 1000) ÷ Volts
Examples
Example 1: Single-Phase Conversion
Convert 10 kVA at 240V.
Amps = (10 × 1000) ÷ 240
Amps = 41.67 A
Example 2: Three-Phase Conversion
Convert 25 kVA at 400V 3-phase.
Amps = (25 × 1000) ÷ (1.732 × 400)
Amps = 36.06 A

FAQs
1. How many amps is 1 kVA?
It depends on the voltage.
- At 240V single-phase: 4.17 A
- At 400V 3-phase: 1.44 A
- At 480V 3-phase: 1.20 A
2. How many amps is 75 kVA 3 phase?
At 480V three-phase: 90.15 amps.
At 400V three-phase: 108.2 amps.
3. What is the formula for 3-phase kVA to amps?
Amps = (kVA × 1000) ÷ (√3 × Volts).
4. How does kVA relate to amps?
kVA measures apparent power.
Amps measure electrical current.
kVA tells you how much power a system can deliver.
Amps tell you how much current is flowing.
More kVA usually means more amps, depending on voltage.
5. How to calculate kVA to amps formula?
Use these formulas:
- Single-phase: Amps = (kVA × 1000) ÷ V
- Three-phase: Amps = (kVA × 1000) ÷ (1.732 × V)
