Frequently Asked Questions

How many amps is 210 kW at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 210 kW equals 356.6 Amps at an industrial power factor of 0.85 (or 303.11 Amps at unity power factor 1.0).

What size breaker and wire is needed for 210 kW at 400V?

For 356.6A continuous load, NEC requires a 125% rated breaker of 450A with 500 kcmil copper conductors, while IEC standard sizing uses a 400A breaker with 240 mm² copper cable.
