(*)  The maximum current rating will be determined according to the number of contacts and the admissible heating.

By continuous duty when n contacts carry I amperes, the temperature increase is roughly:

0.5°C x n for I = 2 A

2.5°C x n for I = 5 A

4.5°C x n for I = 7 A

(A current of 7A or more must not be passed through more than 50% of the contacts on a 27 cts connector at the same time.)
