Schneider Electric QO230 Two Pole Circuit Breaker

Schneider Electric's QO230 is a plug-on two-pole miniature circuit breaker in the Square D QO family. It provides 30 A protection for 120/240 V circuits and carries a 10 kA interrupting rating, enabling rapid disconnection of faults on standard residential or light commercial feeders. As a QO-type device, it is designed for direct installation into compatible QO load centers, offering thermal-magnetic overcurrent protection across both hot legs in a 240 V circuit. The QO230 is intended for plug-on use in Schneider Electric QO panels and similar compatible panelboards, serving as a reliable replacement or upgrade for two-pole 30 A circuits, such as 240 V appliance or range circuits, where panel labeling permits. Plug-on QO breakers are designed for use in QO load centers and are widely supported within Schneider Electric's breaker lineup, providing straightforward installation without separate mounting accessories. This model's 30 A rating and 120/240 V operation make it suitable for protecting branch circuits that feed 240 V appliances or equipment, aligning with common residential and light commercial electrical distributions.
