Schneider Electric QOU230 Circuit Breaker

Schneider Electric QOU230 is a unit-mount, two-pole miniature circuit breaker in the Square D QOU family. It protects 120/240 V AC branch circuits with a 30 A rating and uses a thermal-magnetic mechanism that combines a long-time trip for overload protection with an instantaneous trip for short-circuit protection. With a 10 kA interrupting rating at 240 V, it provides robust fault-current handling for typical residential and light commercial panel installations. Designed for reliable, code-compliant overcurrent protection in 120/240 V systems, the QOU230 is suitable for protecting feeders and individual circuits in Square D QOU panels or compatible enclosures, delivering compact, straightforward protection without sacrificing performance.
