Frequently Asked Questions

How many amps is 100 kVA at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 100 kVA equals 144.34 Amps at an industrial power factor of 0.85 (or 144.34 Amps at unity power factor 1.0).

What size breaker and wire is needed for 100 kVA at 400V?

For 144.34A continuous load, NEC requires a 125% rated breaker of 200A with 1/0 AWG copper conductors, while IEC standard sizing uses a 150A breaker with 50 mm² copper cable.
