We supply liquid filled pad mounted distribution transformers. 112.5 kVA or 150 kVA three phase pad mounted. See three phase ratings and single phase ratings.
Full load current
| Configuration | Full load current |
|---|---|
| 480 V three phase | 150 A |
| 208 V three phase | 347 A |
| 240 V single phase | 521 A |
Nameplate full load current, computed from the standard formula. Free to cite with a link to this page. Any other rating, use the kVA to amps calculator.
What this rating is
125 kVA is a dry type and IEC rating rather than a US standard pad mounted one. The US standard either side is 112.5 kVA and 150 kVA.
About 150 amps at 480 volts three phase. The gap between 112.5 and 125 is small enough that 112.5 usually covers the load, and it is a stocked standard size.
Common questions
How many amps is a 125 kVA transformer
About 150 amps at 480 V three phase. About 347 amps at 208 V three phase. About 521 amps at 240 V single 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 125 kVA transformer used for
125 kVA is a dry type and IEC rating rather than a US standard pad mounted one. The US standard either side is 112.5 kVA and 150 kVA.
Is a 125 kVA transformer pad mounted
No, it is a dry type or iec unit rather than a liquid filled pad mounted transformer. 112.5 kVA or 150 kVA three phase pad mounted.
