Schneider Electric QOU1302102 U Circuit Breaker

Schneider Electric's Square D QOU1302102 U is a 30A, 1-pole miniature circuit breaker designed for unit-mount installation in 120/240VAC circuits. As part of the QOU unit-mount family, it provides overcurrent protection and switching for branch circuits in Square D panels designed to accept unit-mount breakers. The model's "U" designation indicates the unit-mount mounting style, distinguishing it from plug-on QO breakers, and it carries a 10 kA interrupt rating typical of QOU units used in residential and light-commercial panels. Intended applications include protecting lighting and receptacle circuits, small-appliance runs, and other branch circuits in main distribution panels or subpanels that specify QOU unit-mount breakers. This specific device is one option within Schneider Electric's QOU lineup for reliable, compact protection in spaces where a single-pole 30A device is required.
