So what’s the communications connector? Just a thermistor or is there some kind of CMS in there?

Im contacting Eaton now about that. It seems there are 2 versions, the R and T. T integrates a temperature sensor, it seems I purchased the R model, which also has these leads.

I tried to meter these connections but did not have any success in determining their exact purpose.
