Do not confuse AF with DF
The “AF” suffix matters: BRP120AF supplies AFCI protection only. It does not include the GFCI protection found in Eaton BRP120DF. If the circuit design requires both functions at the breaker, compare the exact catalog number before purchasing instead of relying on the similar enclosure and green test-button area.
Final Type BR fit check
Confirm that the loadcenter label permits this Eaton BR plug-on-neutral breaker, then match the catalog number, 20A rating, pole count, voltage, conductor range, and interrupting capacity. Similar-looking breakers from another family are not automatically approved substitutes. A qualified person should confirm application and installation against the equipment instructions and governing electrical code. The chosen variant controls the condition supplied.
