The contact resistance per pole for C60 range of MCBs is as tabulated below:
 
C60 Test for In at 50 Hz, Value per pole
 
Rated Current (A)Impedance (milliohm)
0.58800
0.755267
12300
1.21667
1.5933
2638
3248
4150
5100

757.14
843.25
1017
1311
1510
1610.13
207.35
254.88
303.47
323.47
352.57
402.88
501.9
601.5
631.52

 Note: The resistance is equivalent to the impedance as the inductance between the contacts is negligible.
