Eaton / Cutler-Hammer BRC120AF AFCI Miniature Circuit Breaker

This breaker is designed specifically for Eaton and Cutler-Hammer Type BR load centers. It requires a 1-inch space and uses a standard plug-on connection to the bus bar.

Yes. Because the Eaton BR frame is backward compatible, this breaker is a direct replacement for 20A 1-pole AFCI breakers in legacy Bryant, Westinghouse, and Challenger panels that accept 1-inch Type BR breakers.

This breaker utilizes a traditional pigtail neutral. During installation, the coiled white pigtail wire must be connected directly to the panel's neutral bus bar to power the breaker's internal arc-fault circuitry.

Yes. Although this is a pigtail-style breaker, it is fully compatible with newer Eaton PON panels. The installer simply needs to route and terminate the attached white pigtail wire directly to the panel's neutral bus bar.

The terminal lugs on this 20A breaker are rated to accept 14 AWG to 4 AWG conductors. They are compatible with both copper (Cu) and aluminum (Al) wiring.

The AFCI circuitry continuously monitors the branch circuit for unwanted arcing conditions, such as those caused by damaged wire insulation or loose connections. If a dangerous arc is detected, the breaker trips to mitigate fire hazards.

No. This is a 1-pole, 120VAC breaker. It is not designed or rated for 240V applications or shared-neutral multi-wire branch circuits (MWBCs), which typically require a 2-pole breaker with common trip functionality.

The LI designation refers to the breaker's thermal-magnetic protection profile. The Long-Time (thermal) function prevents damage from sustained overloads, while the Instantaneous (magnetic) function clears severe short circuits immediately.
