C60 Test for In at 50 Hz, Value per pole
| Rated Current (A) | Impedance (milliohm) |
| 0.5 | 8800 |
| 0.75 | 5267 |
| 1 | 2300 |
| 1.2 | 1667 |
| 1.5 | 933 |
| 2 | 638 |
| 3 | 248 |
| 4 | 150 |
| 5 | 100 |
| 6 | 75 |
| 7 | 57.14 |
| 8 | 43.25 |
| 10 | 17 |
| 13 | 11 |
| 15 | 10 |
| 16 | 10.13 |
| 20 | 7.35 |
| 25 | 4.88 |
| 30 | 3.47 |
| 32 | 3.47 |
| 35 | 2.57 |
| 40 | 2.88 |
| 50 | 1.9 |
| 60 | 1.5 |
| 63 | 1.52 |
Note: The resistance is equivalent to the impedance as the inductance between the contacts is negligible.
