BA120AFCHH - 20A AFCI Circuit Breaker

BA120AFCHH  - 20A AFCI Circuit Breaker

The BA120AFCHH is a 20 amp, single-pole AFCI breaker designed to protect circuits from arc faults—one of the more common causes of electrical fires. If you’re working on a panel where AFCI protection is required, this is the type of breaker you’re looking for. It’s a bolt-on unit, so it fastens directly to the panel instead of just snapping in. That gives you a more secure connection, which matters over time. You don’t get the same movement or loosening you sometimes see with plug-in styles. This breaker is rated 65kA at 120/240VAC, so it can handle higher fault conditions without issue. That makes it a solid choice not just for typical residential setups, but also in situations where available fault current is higher than average. There’s nothing complicated about it—it installs the way it should, fits where it should, and does what it’s supposed to do.

Key Features and Benefits

• Combination type AFCI protection: (detects both series and parallel arc faults)
• 20 amp, 1-pole breaker: for standard branch circuits
• 65kA interrupt rating: for higher fault current environments
• Bolt-on mounting: for a tighter, more secure fit in the panel
• Narrow profile: doesn’t take up extra space
• Built for steady, predictable operation

Material Compliance and Certifications

UL Requirements: This breaker is manufactured to meet UL requirements for molded case circuit breakers and AFCI devices, so it’s suitable for installations where code compliance is required.

Where It Works Best

You’ll typically see this used in residential panels where AFCI protection is required—bedrooms, living areas, and similar circuits. It also works in light commercial panels that use bolt-on breakers.
