Siemens 20A Single-Pole Dual Function Circuit Breaker, Combines AFCI/GFCI

The Siemens 120V single-pole dual function circuit breaker combines AFCI (Arc Fault Circuit Interrupter) and GFCI (Ground Fault Circuit Interrupter) protection in a single device to help safeguard against both arc faults and ground faults. Featuring an advanced self-test and lockout function, the breaker continuously monitors itself to ensure proper operation. If a fault is detected within the device, it will automatically trip and prevent reset until the issue is resolved. Designed to meet 2014 National Electrical Code requirements for both arc fault and ground fault protection on kitchen and laundry circuits, this breaker offers enhanced safety, simplified installation, and reliable performance.
