Schneider Electric BO360 Bolt On Circuit Breaker

Schneider Electric's Square D QOB360 bolt-on circuit breaker is a 60-amp, 240-volt, three-pole unit built for bolt-on mounting in compatible Square D QO panelboards. It provides three-phase protection with a 10 kA interrupting rating at 240 V and accepts conductors from 8 AWG to 2 AWG for copper or aluminum wiring, depending on lug configuration. This 3P 60A breaker is intended for feeders and branch circuits in 240 V three-phase distributions, where reliable fault interruption is required. The QOB360 is part of Square D's QOB bolt-on family, offering a bolted-in alternative to plug-in breakers for panels that require three-phase protection across all phases. For installation, ensure you are using a panel that supports QOB bolt-on breakers and follow the manufacturer's torque specs and wiring practices. This model is commonly used in 3-phase distribution panels in commercial/industrial settings where a 60 A, 240 V protection device is needed for feeders or multi-location branch circuits.
