Frequently Asked Questions

How many amps is 150 kVA at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 150 kVA equals 216.51 Amps at an industrial power factor of 0.85 (or 216.51 Amps at unity power factor 1.0).

What size breaker and wire is needed for 150 kVA at 400V?

For 216.51A continuous load, NEC requires a 125% rated breaker of 300A with 4/0 AWG copper conductors, while IEC standard sizing uses a 225A breaker with 95 mm² copper cable.
