kVA to Amps Calculator
Quickly convert kVA to Amps for single-phase and three-phase systems. Use our easy calculator for 120V, 230V, 400V, and more. Ideal for engineers and electricians.

Quick Intro: Convert kVA to Amps
To convert kVA to amps, use the formula that considers system voltage and phase type. For single-phase systems, divide kVA by voltage and multiply by 1000. For three-phase systems, divide by the product of voltage and √3 (~1.732). This formula allows fast and reliable current estimation, aiding in proper electrical design and safety. Simply enter the kVA and voltage values to get accurate amps, crucial for transformer selection, circuit protection, and load balancing.
Formula to Convert kVA to Amps
Single-phase: Amps = (kVA × 1000) ÷ Voltage
Three-phase (line-to-line): Amps = (kVA × 1000) ÷ (√3 × Voltage)
Three-phase (line-to-neutral): Amps = (kVA × 1000) ÷ (3 × Voltage)
kVA to Amps Calculator Overview
The kVA to Amps Calculator converts apparent power measured in kilovolt-amperes (kVA) into current measured in amperes (A). It supports both single-phase and three-phase electrical systems. This calculator helps electricians, engineers, and students quickly find the current flowing through a circuit by simply inputting the kVA rating and system voltage. It is especially useful for designing electrical systems, sizing conductors, and ensuring safe load capacities. The tool is accurate for 50Hz and 60Hz systems and requires no complex inputs like power factor unless converting to real power (kW). Whether for residential or industrial applications, this calculator simplifies your electrical calculations and saves time.
