Schneider Electric QOB230 2-Pole Circuit Breaker

Schneider Electric's Square D QOB230 is a 30 A, two-pole miniature circuit breaker in the QO family. It is designed for bolt-on mounting in compatible QO panels and provides 120/240 V AC protection with a 10 kA interrupting capacity, making it suitable for branch circuits that may experience short circuits or overloads. The QOB230 features Visi-Trip trip indication, a visual cue that the device has opened to interrupt the circuit. As a bolt-on variant of the QO line, it delivers thermal-magnetic protection for residential and light commercial circuits, commonly used for lighting, receptacle, and appliance runs that require 30 A protection. The two-pole configuration ensures simultaneous disconnection of both ungrounded conductors in a 240 V circuit, supporting safety and code-compliant wiring. This model is widely stocked by Schneider Electric and authorized distributors and is compatible with standard QO panel hardware, offering a straightforward replacement or addition to existing Square D installations.
