BA120AFCH - 20A AFCI Circuit Breaker

BA120AFCH  - 20A AFCI Circuit Breaker

The BA120AFCH is a 20 amp, single-pole, bolt-on molded case circuit breaker designed to provide advanced branch circuit protection in residential and light commercial electrical systems. Built on the dependable BAFH2 frame, this breaker delivers a high interrupting capacity of 22kA at 120/240VAC, helping safeguard wiring and connected equipment against overloads and short circuits. What sets this model apart is its Combination Type Arc-Fault Circuit Interrupter (AFCI) protection, engineered to detect both parallel and series arc faults—conditions that traditional breakers may not identify. For property owners and electrical professionals focused on code compliance and fire prevention, the BA120AFCH offers a dependable, code-aligned solution that enhances safety without sacrificing performance or reliability.

Designed for bolt-on panelboard installation, this breaker provides a secure mechanical and electrical connection, helping reduce the risk of loose terminations and improving long-term system stability. Its compact, single-pole configuration makes it an efficient choice for protecting individual 120V branch circuits, while the 20A rating aligns with common residential lighting and receptacle loads. Whether you're upgrading an existing panel or completing a new installation, the BA120AFCH supports modern safety standards while delivering consistent, high-level protection.
