What is the contact resistance per pole for C60 range of MCBs.

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)
0.5 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.
