A transition has been made in the standard from UL508 to UL 60947-4-1, in order to harmonize with the IEC standard.

ComPacT NSX complies with this UL 60947-4-1 standard for performance levels F, N, and H. So not for B.

Therefore, you should select for example C10F4 to be compliant.

This is also indicated on pages A-6 and A-7 of the catalog. In the Belgian Dutch-language and French-language catalog, you will still find UL508, while the English-language catalog mentions UL 60947-4-1.
