Hi,
You may look at FAQ to see information regarding the matter.
In general, Vigi version of the RCD is the best option, using the SI type. See page 39 of the RCD Technical guide:

As for the mcb, acti9 are rated 400HZ as well. However, the magnetic trip increased, thereby longer short circuit protection.
See extract from CA908005E catalog attched.
