Circuit Breaker AFCI 20A 1-Pole 120V Plug-In CSA Approved · Siemens QA120AFCCSA
20A single-pole combination AFCI breaker for 120V branch circuits in Siemens Q series loadcentres where this breaker is listed. It helps detect arc faults to reduce fire risk and is CSA approved for use in Canada.
What this product is for
This is a 20A, 1-pole combination arc-fault circuit interrupter (AFCI) breaker for 120V branch circuits. It is used to add arc-fault protection in compatible Siemens loadcentres for residential and light commercial applications in Canada.
Use for
Use for bedroom, living area, hallway and other branch circuits where AFCI protection is required by the applicable electrical code and the panel listing permits this breaker. Commonly used on 20A circuits with #12 AWG copper conductors.
Avoid for
Do not use where a standard thermal-magnetic breaker, GFCI breaker, or dual-function breaker is specifically required instead. Do not assume compatibility with non-Siemens panels or with Siemens panels not listed for Type QA or QAF2 style breakers.
Best for
Best for service upgrades, panel retrofits, and branch-circuit protection where a 20A single-pole AFCI breaker is needed and CSA approval for Canada matters.
Installed in
Installed in compatible Siemens loadcentres and panelboards that accept this plug-in breaker format. The breaker is typically used on 120V single-phase branch circuits.
Why this product exists
Combination AFCI breakers are designed to detect hazardous arcing conditions and open the circuit before they can develop into an electrical fire. This model provides that protection in a 20A, 1-pole format for listed Siemens systems.
Compared with similar products
Compared with a standard breaker, this unit adds arc-fault protection. Compared with a dual-function breaker, it does not add Class A GFCI protection. Compared with newer plug-on-neutral Siemens variants, this SKU is commonly listed as the CSA version for Canada and should be selected by exact part number and panel compatibility.
Typical trade guidance: 20A branch circuits are commonly paired with #12 AWG copper. Actual conductor sizing, breaker selection, and code requirements depend on installation conditions, equipment listing, and local electrical code.
