It is not possible to use CSH30 with the VIP410 relay. CSH30 is used to cooperate with standard 1A5A CT, which should be connected to the secondary of standard CT. Here is an example:

But for VIP410, use core balance CT CSH200/CSH120/GO110/CSHU to connect the current cable directly.

So CSH30 is a totally different CT from CSH200/CSH120/GO110/CSHU. it can not be used for VIP410 for earth fault current measurement.
