CHFP120AF is an Eaton CH part, not a BR part. It is a 20A, single-pole combination AFCI breaker built with Eaton’s CH plug-on-neutral connection. That family distinction is central to choosing the correct device because CH and BR catalog numbers are not interchangeable.

Why the CH prefix matters
The CHFP120AF is AFCI-only. It should not be confused with a dual-function breaker that adds Class A ground-fault protection, or with an Eaton BR plug-on-neutral AFCI carrying a BRP catalog number. Matching the printed model prevents those three different choices from being collapsed into one.
Verify the loadcenter, then the circuit
Use the Eaton loadcenter label to confirm an approved CH plug-on-neutral breaker. Check the 20A rating, single-pole 120V circuit, 10 kAIC requirement, and conductor limits shown by the equipment. Similar handles and footprints do not establish compatibility. A qualified installer should confirm the application before energizing the circuit.
