Description
Part of the QO series, this 15A dual function breaker combines Class A 6mA ground-fault and combination arc-fault protection. The Square D QO115PAFGF is engineered specifically for QO plug-on neutral load centers, streamlining installation by eliminating the pigtail connection. Serving as the direct replacement for the legacy QO115PDF, it operates at 120V with a 10kAIC rating. It includes the Visi-Trip visual indicator to easily spot tripped circuits.Specifications

Product FAQs
7 answersCan I install the QO115PAFGF in a standard Square D QO load center?
No. This breaker is designed specifically for QO Plug-On Neutral load centers. Standard QO panels do not have the specialized neutral bus bar required to accept the plug-on neutral clip of this breaker.
What is the pigtail equivalent of this breaker for standard QO panels?
If your panel does not support plug-on neutral breakers, you can use the Square D QO115DF. It provides the same combination arc-fault and ground-fault protection but uses a standard pigtail wire to connect to the panel neutral bar.
Does this model replace the discontinued QO115PDF?
Yes, the QO115PAFGF is the direct manufacturer replacement for the obsolete QO115PDF and QO115PDFCS dual function circuit breakers.
What levels of ground fault and arc fault protection does this dual function breaker offer?
The QO115PAFGF provides both Combination Arc Fault Circuit Interruption (CAFCI) and Class A 6mA Ground Fault Circuit Interruption (GFCI) in a single device, helping meet National Electrical Code (NEC) requirements for dual protection on applicable circuits.
How does the plug-on neutral design change the installation process?
This breaker clips directly onto the specialized neutral bus bar of a compatible QO panel. This eliminates the need to route and terminate a curly pigtail wire, resulting in a faster installation and a less cluttered panel gutter.
How do I use the Time Saver Diagnostics feature to troubleshoot a tripped circuit?
Turn the circuit breaker off, hold down the test button, and move the handle back to the on position. An instant trip indicates a ground fault. A 2.0 second delay indicates an arc fault. A 5.0 second delay indicates a thermal overload, a short circuit, or no fault.
Can the QO115PAFGF be used on a shared neutral circuit?
No. Because this breaker includes Class A ground fault protection, sharing a neutral across two single-pole breakers will cause an imbalance. This will result in an immediate trip during operation.
