How kW to Amps at 440V 3 Phase Works

1

Enter the load power in kW

Use the rated power from the motor nameplate or load schedule.

2

Confirm voltage is 440V

440V is commonly used in India, parts of Asia, and older industrial installations. The calculator is pre-set to 440V.

3

Enter the power factor

Use PF 0.85 for motors. Industrial plants with power factor correction capacitors may operate at PF 0.95.

4

Read the line current

The result is the balanced per-phase current for sizing cables and switchgear.

kW to Amps at 440V 3 Phase Formula

440V 3-PhaseI = (kW × 1000) ÷ (1.732 × 440 × PF)

Standard formula for 440V three-phase systems.

Quick MultiplierAmps ≈ kW × 1.31 (at PF 1.0)

At 440V 3-phase PF 1.0, multiply kW by 1.31.

ReversekW = (1.732 × 440 × I × PF) ÷ 1000

Convert amps back to kilowatts at 440V three-phase.

At 440V three-phase, 1 kW equals 1.31 amps at PF 1.0, or 1.54 amps at PF 0.85.

440V three-phase is widely used in India, parts of Southeast Asia, and some older US industrial installations. In India, the Bureau of Indian Standards (BIS) specifies 440V as the nominal three-phase industrial voltage. Many motor nameplates in these regions are rated for 415V/440V ± 10%.

Frequently Asked Questions

7.5 kW at 440V three-phase with PF 0.85 equals 11.58 amps per phase.

No. 440V and 415V are different nominal voltages. In practice, the supply voltage at the terminals varies. Always use the actual measured voltage for accurate calculations.

The standard three-phase industrial voltage in India is 440V (line-to-line). Single-phase is 230V (line-to-neutral).

Use the formula I = (kW × 1000) ÷ (1.732 × 440 × PF). For a 5.5 kW motor at PF 0.85, the current is 8.49 amps.
