Schneider Electric QOB2125VH Miniature Circuit Breaker

The Schneider Electric Square D QOB2125VH miniature circuit breaker is a 2-pole bolt-on MCB rated at 125 A for 120/240 VAC service, delivering a 22 kA interrupting capacity to handle high fault currents in commercial panels that accept QOB devices. Designed for bolt-on mounting, it locks into Square D/QOB installations where high-current protection is required for a paired hot conductor in a single-phase circuit. The QOB2125VH includes VisI-Trip visual trip indication, so the tripped state is easily verified without removing the cover. As part of the QO/QOB family, this breaker provides coordinated overcurrent protection for individual branch circuits within panels compatible with QOB hardware, and it ensures simultaneous trip of both poles for complete isolation of the protected circuit in 120/240 V systems. Suitable for use in main distribution panels or subpanels that accept bolt-on breakers, this unit is intended for environments demanding reliable, high-current protection for heavy loads, heaters, motors, or other demanding branch circuits.
