B220AFCH - 20A AFCI Circuit Breaker

B220AFCH  - 20A AFCI Circuit Breaker

The B220AFCH is a 20 amp, 2 pole, bolt-on molded case circuit breaker designed to deliver dependable circuit protection with advanced Combination Type Arc-Fault Circuit Interrupter (AFCI) technology. Built on the BAFH2 frame, this breaker is engineered to detect both parallel and series arc faults, helping reduce the risk of electrical fires caused by damaged wiring, loose connections, or insulation breakdown. With an interrupting capacity of 22kA at 120/240VAC, it offers strong protection for residential and light commercial electrical systems where safety, reliability, and code compliance matter most. Designed for secure bolt-on installation, the B220AFCH provides a stable connection to the panelboard, helping ensure consistent performance under load.

Whether you’re upgrading an existing panel or installing new branch circuits, this breaker delivers dependable overcurrent and arc-fault protection in one compact unit. Its 20 amp rating makes it ideal for common branch circuits, while the dual-pole configuration supports 120/240V applications requiring multi-wire branch circuit protection.
