Eaton Cutler-Hammer Plug-On Neutral (differences)
Eaton - Catalog numbers still to come

I found this, not sure where though. The last page has "March 2019".

Example: 

New plug-on neutral catalog number is:


CHFP120DF


Similar previous design catalog numbers:


CHFAFGF120PN
CHFAFG120


Now if I could only find these two AFCI Plug-On Neutral breakers:


CHFP115AF (AFCI 15 Amp)
CHFP120AF (AFCI 20 Amp)
