BA120AFCHH - 20A AFCI Circuit Breaker

BA120AFCHH  - 20A AFCI Circuit Breaker

The BA120AFCHH is a 20 amp, single-pole bolt-on circuit breaker designed to provide both overcurrent protection and advanced arc-fault protection in 120/240VAC systems. As a Combination Type Arc-Fault Circuit Interrupter (AFCI), it detects dangerous arc conditions—both series and parallel—that can lead to electrical fires. This makes it a smart choice for installations where code-compliant arc-fault protection is required and safety is a priority. With a 65kA interrupting rating at 120/240VAC, this breaker is built for applications where available fault current is high. The bolt-on mounting style provides a firm, stable connection to compatible panelboards, helping ensure consistent electrical contact over time. Built on the HBAF2 frame, the BA120AFCHH is suited for commercial and industrial environments where reliability matters. Whether you're replacing a failed breaker or outfitting a panel that requires AFCI protection, this unit delivers dependable performance without overcomplicating installation.
