Neutral Current Transformer

Hello,

I could not find a neutral current transformer compatible with Pro-3EM-3CT63 matter.

Based on the thread Additional current tranformer for Neutral measurements it seems that if I bought EM3 50A transformer and added a connector to it, (fuse limit current to 16A, so 50A is enough in my case), but it was focused on 50A and 120A clamps, I have no clue whether the same apply to 3CT63A version.

Calamar Any hints or practical experience?

An additional question is, what is the added value of measuring the neutral wire current, will it helps to the measurement precision or is it intended just for cases where improper wiring is expected to be abe to detect energy leaks?

Thanks a lot!
