Square D QO120PLILC 20A 1P Circuit Breaker, AFCI, GFCI, Dual-Function | AmpState

< p>Introducing the Square D QO120PLILC—the 20A, 1-pole circuit breaker that brings dual-function AFCI and GFCI protection to your panelboards and load centers. Built for everyday electrical work, this compact device delivers reliable arc-fault and ground-fault protection in a single unit, helping you meet modern codes without sacrificing space in the distribution panel.

What makes this breaker stand out is its practical, job-ready design. The QO120PLILC is specifically tailored for maintenance teams, panel builders, and spare inventory where a direct part-number match matters. When you need a precise replacement that fits the Square D QO family, this is your go-to choice.

Key advantages

• Direct part-number match: Ensures compatibility in existing QO load centers and panelboards, minimizing guessing during maintenance or stocking.
• Code-ready versatility: Ideal for circuits where both arc fault and ground fault protection are required, helping you meet safety standards in residential and light commercial applications.
• Trusted manufacturer: Square D’s QO-series reliability with a design that fits standard QO panels for straightforward replacement and upgrades.
• Available from AmpState: A dependable source for part numbers and compatibility confirmation—message the team if you need help verifying fit.

Why choose this over alternatives

With a direct fit into Square D QO panels, it offers a reliable, code-compliant solution that installers can trust from first fit to future maintenance.

Before installation, confirm that your panel is compatible with the QO series and that the slot is appropriate for a 1-pole, 20A device.
