Schneider Electric QOB250VH Bolt-On Circuit Breaker

Schneider Electric's QOB250VH is a 50-amp, two-pole miniature circuit breaker in the QO bolt-on family, designed for 120/240-volt AC service in compatible Schneider Electric panel configurations; as a bolt-on device it installs by securing the breaker to the panel's internal bus bars with a mounting screw, delivering a single, combined ON/OFF handle action for both poles. Equipped with a thermal-magnetic trip mechanism, it provides overload protection and an instantaneous short-circuit response, and it carries a 22 kA short-circuit current rating at 120/240 VAC, making it suitable for branch circuits where higher fault currents are expected; the 2-pole design ensures simultaneous disconnection of both live conductors for enhanced safety. The QOB250VH is intended for bolt-on installation in QO-style panels and enclosures that accept QOB devices, matching the QO family footprint for straightforward replacement and upgrades on 50 A circuits in residential and light commercial applications.
