Siemens QAF 15-amp 2-Pole Combination Arc Fault Circuit Breaker

The Siemens 15-Amp 2-Pole Combination AFCI Circuit Breaker reduces wiring costs and installation time by enabling contractors to use multi-wire branch circuits, commonly known as “shared neutrals”. When using single pole CAFCIs, a dedicated neutral is required for each circuit. This breaker allows electricians to share neutrals between the two circuits fed by the breaker. CAFCI Breakers are designed to protect against line-to-ground arcs, line-to-neutral arcs and series arcs to help protect your home from an electrical fire. The breaker is intended to mitigate the effects of arcing faults by de-energizing the circuit when an arc-fault is detected.
