Product FAQs
5 answersCan I use the BA120AFC in standard residential load centers?
No. The BA120AFC is a bolt-on breaker designed specifically for commercial Siemens P1, P2, and P3 panelboards. Standard residential load centers typically require plug-in style breakers.
Does this breaker require a plug-on neutral panel?
No, the BA120AFC features a pigtail neutral connection. The pigtail wire routes directly to the neutral bus bar, allowing installation in standard panels without plug-on neutral capabilities.
What type of arc fault protection does the BA120AFC provide?
It is a Combination Type AFCI. This means it detects and mitigates both parallel and series arcing faults, offering more comprehensive protection than older branch/feeder AFCI models like the BA120AF.
Are there higher interrupting rating versions of this breaker available?
Yes. While the BA120AFC provides a standard 10kAIC rating, Siemens manufactures the BA120AFCH for 22kAIC systems and the BA120AFCHH for 65kAIC requirements.
Does the BA120AFC include diagnostic indicators?
Yes, it features built-in LED trip indicators to help electricians and maintenance personnel quickly identify the specific cause of a fault condition after a trip.
