QO115PAF selection note: This Square D QO device is a 15A combination arc-fault breaker with a plug-on-neutral connection. It is intended for QO equipment specifically identified for the plug-on-neutral format and protects against qualifying arc-fault conditions in addition to normal overload and short-circuit operation.

What “PAF” does—and does not—mean
QO115PAF supplies combination arc-fault protection; it is not a dual-function GFCI/AFCI breaker. Schneider Electric lists it as the successor to legacy QO115PCAFI. If ground-fault protection is also required at the breaker, a different exact catalog number is needed.
QO compatibility checkpoint
Read the panel label for the permitted QO breaker and plug-on-neutral families. Match 15A, one pole, 120V, protection type, and interrupting capacity to the circuit design. Do not substitute a Homeline breaker or another brand on the basis of a similar shape. Installation should follow Square D instructions and be completed by a qualified person.
