Frequently Asked Questions

How many amps is 650 kVA at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 650 kVA equals 938.19 Amps at an industrial power factor of 0.85 (or 938.19 Amps at unity power factor 1.0).

What size breaker and wire is needed for 650 kVA at 400V?

For 938.19A continuous load, NEC requires a 125% rated breaker of 1200A with 2× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 1000A breaker with 2× 400 mm² copper cable.
