Thank you for your interest in our product lines. Our CRD4100 Data Stream RS485 Digital Current Transducer will for your application. However, we do not have this package in a split core. You can use a two part solution with a 5 amp secondary split core and short the leads thru the aperture of the transducer. I have attached the catalog pages of our CRD4100 Series, 604 Series Split Core Current Transformer and our application guide for the two part solution.
