45 kVA full-load current
| Voltage | Amps |
|---|---|
| 120 V single-phase | 375.0 A |
| 240 V single-phase | 187.5 A |
| 208 V three-phase | 124.9 A |
| 240 V three-phase | 108.3 A |
| 480 V three-phase | 54.1 A |
| 600 V three-phase | 43.3 A |
Single-phase I = kVA × 1000 ÷ V; three-phase I = kVA × 1000 ÷ (√3 × V).
