Product FAQs
5 answersCan I install the BA120AFH in a standard Siemens residential load center?
No. The BA120AFH features a bolt-on connection designed specifically for Siemens P1, P2, and P3 commercial panelboards, rather than plug-on residential load centers.
What does the H in the BA120AFH catalog number indicate?
The H designates a high interrupting rating. This model provides a 22kAIC rating at 120VAC, whereas the standard BA120AF model is rated for 10kAIC.
What type of arc fault protection does this breaker provide?
The BA120AFH provides Branch/Feeder AFCI protection. It is not a Combination AFCI breaker.
What is the combination AFCI equivalent for this model?
If your application requires Combination AFCI protection, the BA120AFCH is the direct replacement for this branch/feeder model.
How is the neutral wire connected on this AFCI breaker?
The BA120AFH utilizes a standard pigtail neutral wire that must be routed and connected directly to the panelboard neutral bus.
