Square D QO120PDF 20A 1P 120V Circuit Breaker, AFCI, GFCI, Dual-Function, Plug-On Neutral, Plug-On | AmpState

Square D QO120PDF is a compact, 20A, 1-pole, 120V circuit breaker that combines AFCI and GFCI protection in one plug-on device. Built for reliability in panelboards and load centers, it’s a trusted choice for residential electrical protection where space and performance matter.

Key features designed to simplify installation and enhance safety:

• Dual-Function Protection—AFCI and GFCI operate together in a single unit, safeguarding against arc faults and ground faults on 120V circuits.
• Plug-On Neutral (PON)—Eases neutral connections, reduces wiring mistakes, and speeds up installation with a cleaner, more secure neutral terminal.
• 1 Pole, 20 Amps—Ideal for standard 120V branch circuits that require reliable overcurrent protection alongside arc-fault and ground-fault detection.
• QO Series Compatibility—Designed for Square D QO panelboards and load centers, helping ensure proper fit and performance in replacement projects.
• Replacement & Stocking Utility—A practical choice for maintaining BOM alignment with the original part number, making repairs and replacements straightforward.

Who benefits most from the QO120PDF? homeowners tackling remodels or upgrades, electrical contractors fitting out new or existing panelboards, and property managers who need dependable, code-compliant protection without clutter or complexity. It’s particularly well-suited for circuits where NEC requirements call for both arc-fault and ground-fault protection in a single, easy-to-install solution.

Practical use scenarios

• Renovating a kitchen or laundry area where AFCI/GFCI protection is recommended for receptacle circuits and small-appliance branches.
• Replacing an aging or non-compliant breaker in a Square D QO panel with a unified AFCI/GFCI device to meet current safety standards.
• Stocking spare parts for maintenance programs that require exact part numbers to keep BOMs intact.
