We haven't got coordination tables for MCBs iC60a.
They are not in the global catalog modules including technical guide LVPED318033EN.
See link to the Complementary Technical Information 2021 - Selectivity, Cascading and Coordination Guide : https://www.se.com/ww/en/download/document/LVPED318033EN/
We cannot use the equivalent data from iC60N because the breakers don't have the same performance.
We can advise to use iC60N breakers instead of iC60a in projects where the implementation of selectivity / coordination will be done.
