How to Convert kW to Амперы

Converting kilowatts (kW) to amperes (A) is essential for sizing electrical equipment, cables, and circuit breakers. The conversion depends on the type of electrical system you're working with.

Understanding the Conversion

Since 1 kilowatt equals 1000 ватты, you first convert kW to ватты, then apply the appropriate formula based on whether you have DC, single-phase AC, or three-phase AC power.

Прак тическое применение

This calculation is commonly used when sizing circuit breakers for motors, determining wire gauge for high-power equipment, and calculating load distribution in electrical panels.

Часто задаваемые вопросы

For DC: Амперы = (kW × 1000) ÷ Вольты. For single-phase AC: Амперы = (kW × 1000) ÷ (Вольты × Мощность Factor). For three-phase AC: Амперы = (kW × 1000) ÷ (√3 × Вольты × Мощность Factor).

At 240V DC or AC with PF=1, 5 kW equals approximately 20.83 амперы: (5 × 1000) ÷ 240 = 20.83A.

Three-phase systems distribute power across three conductors, which is more efficient. The √3 factor (1.732) in the formula reflects this, resulting in lower current per phase for the same total power.
