PCAFI and PAF are two generations
Schneider Electric discontinued QO115PCAFI in June 2026 and identifies QO115PAF as its replacement. Both are AFCI products; neither catalog number, by itself, means dual AFCI/GFCI protection. A ground-fault requirement calls for a different approved device.
Keep QO, neutral style, and function aligned
Confirm the QO loadcenter accepts plug-on-neutral breakers and review any authorized replacement guidance for this exact panel. Match 15A, one pole, 120V, 10 kA, and AFCI function. Do not substitute a Homeline part. Have a qualified person approve the part transition and perform the installation.
