We supply liquid filled pad mounted distribution transformers. 500 kVA or 750 kVA three phase pad mounted are the US standard ratings either side. See three phase ratings and single phase ratings.
Full load current

What this rating is
630 kVA is one of the most common IEC ratings in Europe, Asia and the Middle East, usually at 400Y/230 volts. It has no US equivalent on the standard list.
About 909 amps at 400 volts, which is the voltage it is normally paired with. Searches for it in the US almost always come from imported equipment or an international specification.
Common questions
How many amps is a 630 kVA transformer
About 758 amps at 480 V three phase. About 909 amps at 400 V three phase. About 1,749 amps at 208 V three phase. Three phase current is kVA times 1000 divided by the voltage times the square root of three. Single phase leaves out the square root of three, which is why the single phase figures are much higher.
What is a 630 kVA transformer used for
630 kVA is one of the most common IEC ratings in Europe, Asia and the Middle East, usually at 400Y/230 volts. It has no US equivalent on the standard list.
Is a 630 kVA transformer pad mounted
No, it is a iec standard unit rather than a liquid filled pad mounted transformer. 500 kVA or 750 kVA three phase pad mounted are the US standard ratings either side.
