Schneider Electric QOB3601021 Circuit Breaker

The Schneider Electric QOB3601021 is a three-pole, 60 A miniature circuit breaker in the QOB bolt-on family, rated for 120/240 VAC with a 10 kA interrupting capacity and designed for bolt-on mounting in compatible Square D panels. QOB denotes the bolt-on variant of the QO/QOB mini breakers, intended for use in Schneider Electric load centers and panelboards that accept bolt-on devices. The unit includes a 120 V AC shunt-trip coil, enabling remote tripping for safety interlocks or emergency shutdown schemes. It employs a thermal-magnetic trip mechanism typical of QO/QOB breakers, providing both instantaneous overcurrent protection and overload protection. With a 10 kA interrupt rating at 240 VAC and three poles, it protects three-phase circuits in industrial or commercial installations while conserving panel space. A 10 kA interrupt rating at 240 VAC means it can interrupt faults up to 10,000 A at 240 V, a key spec for protecting three-phase feeders in commercial and industrial panels.
