PCB mount Current Transformer layout
I have used this sort of transformer in PCB layout before. A couple things to note:


Regardless of how you design this, the primary current you want to
measure must pass through the hole in your CT. The secondary side
(the pins that land in the PCB) are the output of the CT.
Since these are low frequency CTs, however you lay them out will probably be OK, provided your schematic is functionally correct.


Depending on your design, there are a couple ways to get the primary current through the CT:


Run your primary wire directly through the CT hole: This is the most obvious, and perhaps one that you wish to avoid?
Provide a terminal block or some other two-pin connector on your board that has two traces run to either side of the CT. A wire or metal clip can then be installed through the CT hole to complete the primary side connection. This is the method I’ve used and have had good success. 


Without further information on your application or other design considerations, it’s hard to give other ideas. Good luck!
