We supply liquid filled pad mounted distribution transformers. Pad mounted transformers start at 25 kVA single phase and 45 kVA three phase. See three phase ratings and single phase ratings.
Full load current
| Configuration | Full load current |
|---|---|
| 480 V three phase | 12 A |
| 208 V three phase | 28 A |
| 240 V single phase | 42 A |
| 120 V single phase | 83 A |

What this rating is
A 10 kVA transformer is a small dry type or control unit. Single phase versions feed lighting circuits, small machines and control panels. Three phase versions appear in small fit outs and equipment skids.
At 240 volts single phase this gives about 42 amps, which is enough for a modest machine or a small subpanel. At 480 volts three phase it is only about 12 amps.
Common questions
How many amps is a 10 kVA transformer
About 12 amps at 480 V three phase. About 28 amps at 208 V three phase. About 42 amps at 240 V single phase. About 83 amps at 120 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 10 kVA transformer used for
A 10 kVA transformer is a small dry type or control unit. Single phase versions feed lighting circuits, small machines and control panels. Three phase versions appear in small fit outs and equipment skids.
Is a 10 kVA transformer pad mounted
No, it is a dry type or control unit rather than a liquid filled pad mounted transformer. Pad mounted transformers start at 25 kVA single phase and 45 kVA three phase.
