160 kVA to Amps
160 kVA is 230.9 A at 400 V and 8.398 A at 11 kV (three-phase), and 695.7 A at 230 V single-phase. Table for common supplies and the formula.
Formula
Worked example
- Three-phase, 400 V: I = 160 × 1,000 / (√3 × 400) = 230.9 A
- Single-phase, 230 V: I = 160 × 1,000 / 230 = 695.7 A
On other supplies
| Supply | Voltage | Current |
|---|---|---|
| Single-phase | 120 V | 1,333 A |
| Single-phase | 230 V | 695.7 A |
| Single-phase | 240 V | 666.7 A |
| Three-phase | 208 V | 444.1 A |
| Three-phase | 400 V | 230.9 A |
| Three-phase | 415 V | 222.6 A |
| Three-phase | 480 V | 192.5 A |

Three-phase rows use the line-to-line voltage.
What 160 kVA looks like
160 kVA is a standard rating in the IEC preferred series of distribution transformers.
This is the rated current only. Cable, breaker and protection settings also depend on the installation, inrush, the rules you work to and the transformer data sheet.
Frequently asked questions
How many amps is 160 kVA?
160 kVA is 230.9 A on a 400 V three-phase supply, 222.6 A at 415 V and 8.398 A at 11 kV. On a 230 V single-phase supply it is 695.7 A. The current depends on the voltage, so there is no single answer.
Why is no power factor needed?
kVA is apparent power, which is voltage times current (times √3 for three-phase). The power factor only matters when you convert kVA to kW.
Is this the rated current of a transformer?
It is the rated line current at that voltage for a balanced load: kVA × 1,000 / (√3 × V). Inrush, overload and fault current are separate questions.
