BA120AFCH - 20A AFCI Circuit Breaker

BA120AFCH  - 20A AFCI Circuit Breaker

If you’re upgrading a panel or replacing a breaker, the BA120AFCH 20-amp AFCI circuit breaker is one of those parts that quietly does a very important job. It’s designed not just to trip when there’s an overload, but to catch arc faults—those small electrical issues that can turn into serious problems if they go unnoticed. This is a combination-type AFCI breaker, which means it detects both series and parallel arc faults. That’s the kind of protection most newer electrical codes call for, especially in living spaces like bedrooms and common areas. The bolt-on design gives it a solid, secure fit in the panel, so you don’t have to worry about loose connections. With a 22kA interrupting rating, it’s built to withstand higher fault conditions without hesitation. It’s compact, straightforward to install, and does exactly what you need it to do—protect your wiring and help reduce the risk of electrical fires.
