Use the links above or do an advanced search in ppubs for:
(375/329.ccls. or 375/330.ccls. or 375/diphase.ccls. or 375/331.ccls. or 375/332.ccls. or 375/333.ccls.)
This will show what classes derive from the input. Ex: entering 43/42.24 shows the derived classes and the search that can be used to find patents or patent applications in those subclasses.
