Square D QO Plug-on Neutral Load Centers and CAFI Circuit Breakers

Schneider QO Plug On Neutral Load Centers CAFI  header

The National Electrical Code continues to expand the number of circuits requiring arc-fault protection. Helping contractors manage arc-fault expansion, QO Plug-on Neutral Load Centers and CAFI Circuit Breakers eliminate the CAFI pigtail, reducing connections and wires in the load center gutter. Simplifying CAFI circuit breaker installation helps contractors save time.

The Square D QO Plug-on Neutral system features an innovative neutral jaw and integrated neutral rail system engineered to replace the traditional pigtail wire connection.

Square D has developed the TIME SAVER indication feature, now standard on all Square D brand CAFI circuit breakers. Square D CAFI circuit breakers remember their last trip; ground fault, arc fault, or thermalmagnetic. In the event of a Combination Arc Fault Circuit Breaker trip, quickly identifying the source of the trip event is key.
