Schneider Electric QOB320VH U Circuit Breaker

Schneider Electric's QOB320VH U Circuit Breaker is a 20 A, three-pole miniature molded-case breaker designed for 240 V three-phase distribution. It is part of the QOB series and features bolt-on mounting for compatible QOB load centers, enabling straightforward installation in industrial control panels. Rated for 22 kA maximum short-circuit current at 240 V, this breaker provides robust protection for branch circuits against overloads and short circuits in commercial and light industrial electrical distributions. The three-pole configuration ensures simultaneous interruption of all three phases, improving protection and preventing phase imbalance. This model is commonly used to protect 3-phase feeders and motor circuits in panel boards and electrical distribution systems that rely on 240 V three-phase power.
