B220AFC - 20A AFCI Circuit Breaker

B220AFC  - 20A AFCI Circuit Breaker

The B220AFC is a 20 amp, 2 pole, bolt-on molded case circuit breaker designed to deliver dependable overcurrent and advanced arc-fault protection in 120/240VAC electrical systems. Built on the BAF frame platform and rated at 10kA A.I.C., this Combination Type Arc-Fault Circuit Interrupter (AFCI) helps safeguard branch circuits from both parallel and series arc faults—conditions that traditional breakers are not designed to detect. Ideal for residential and light commercial panelboards, the B220AFC provides code-compliant arc-fault protection while maintaining the performance and durability expected from a high-quality molded case circuit breaker. If you’re upgrading an existing panel or replacing a faulty breaker, this unit offers the protection and reliability today’s electrical systems demand.

Key Features and Benefits
