Schneider Electric QOB240VH Bolt On Circuit Breaker

Schneider Electric's Square D QOB240VH is a bolt-on, two-pole miniature circuit breaker rated 40 A for 120/240 VAC circuits. Designed for QOB bolt-on installations in panelboards such as NQO and NQOD, this unit provides a 22 kA short-circuit interrupting rating at 120/240 VAC and features a distinctive yellow housing for easy identification. Mounting is by bolting directly to the panel interior (bolt-on), as opposed to plug-in QO devices, and the two-pole design interrupts both hot legs of a 240 V circuit to protect feeders and branch circuits. The QOB240VH is part of the QOB family within Schneider Electric’s Square D line and is appropriate for commercial or light industrial panel configurations that specify bolt-on protection. This model accepts standard 120/240 V single-phase loads and carries a 40 A rating, making it suitable for circuits such as large appliances or feeders that require robust overcurrent protection in compatible panelboards. In summary, the QOB240VH provides reliable 40 A, 2-pole protection for 120/240 V circuits in bolt-on QOB installations, with a 22 kA interrupting capacity and a yellow, bolt-on form factor that distinguishes it from plug-in breakers.
