Schneider Electric QOU230U Two-Pole Circuit Breaker

Schneider Electric's QOU230U is a two-pole miniature circuit breaker rated for 30 A at 120/240 V AC, part of the QOU family designed for standard unit-mount panels. It delivers a 10 kA interrupt rating and uses a thermal-magnetic trip to provide both long-time and instantaneous protection for dual-pole circuits. This 240 V breaker is suitable for protecting branch circuits in residential and light commercial panels, where simultaneous disconnection of both hot conductors is required for safety. Common applications include protecting 240 V loads such as HVAC equipment and other large-appliance circuits in distribution panels, where reliable protection and compatibility with QOU-standard panels are required.
