Combination Arc Fault Circuit Interrupters
Combination arc fault circuit interrupters (CAFCIs) provide protection against series and parallel arcs. Arcing is a precursor to many electrical fires. Square D QO CAFCIs help protect people and property from fires caused by electrical arcing. These devices continuously monitor the branch circuit and trip when a potentially dangerous condition is detected.
Dual Function (CAFCI + GFCI)
The innovative Square D QO dual function circuit breakers combine two state-of-the-art technologies — Combination Arc Fault and Ground Fault (class A) protection — into one circuit breaker. Dual function circuit interrupters provide a higher level of protection than any other residential circuit breaker. Where installed, these devices protect the entire circuit, not just a part of the circuit like electronic receptacles do.
