The Sensor IQ Smartbreakers have a label on one of the flat sides that identifies the breaker ratings as well as the ETC part number for that breaker type.  

The Part number can be found on the third (3rd) line from the bottom of the label.  The breaker will need to be removed from the panel to see the label.  This part number consists of the letters "CB", followed by an array of numbers, possibly finishing with a "-" suffix.  If you are asked for the part number of the Sensor IQ breakers, please provide the full part number.  in the image below, you can see the part number circled in red.  The full part number is "CB852-1D".
