B120DFH - 20A Dual Function Circuit Breaker

B120DFH  - 20A Dual Function Circuit Breaker

When you need dependable circuit protection that checks all the right boxes for today’s electrical codes, the B120DFH 20 amp breaker delivers. This single pole, bolt-on molded case circuit breaker combines Combination Type AFCI and 5mA GFCI protection into one unit, helping protect against arc faults, ground faults, and overloads in a single, space-saving solution. Rated for 120/240VAC with a 22kA interrupting capacity, it’s built to safely clear high fault currents while providing the level of protection required in many modern residential and light commercial applications.

Instead of installing separate devices for arc-fault and ground-fault protection, the B120DFH simplifies the setup. It’s especially useful in areas where both protections are required, helping electricians and property owners meet code while keeping the panel clean and organized. The bolt-on design also provides a secure, stable connection inside compatible panelboards.

Key Features and Benefits
