Schneider Electric QOB230 Bolt-On Circuit Breaker

Schneider Electric's Square D QOB230 bolt-on circuit breaker is a 2-pole, 30A miniature breaker rated for 120/240 VAC with a 10 kA interrupting capacity. Designed for bolt-on mounting in QO-series panels and enclosures, it provides thermal-magnetic overcurrent protection for branch circuits such as lighting, receptacles, and small-appliance circuits that require 30A protection. This 2-pole device interrupts both hot legs in a 120/240V system, and its bolt-on format supports secure, field-replaceable installation within compatible Square D equipment. As part of the QO family, the QOB230 serves as a standard replacement option for existing bolt-on configurations in compatible panels, aligning with common electrical distribution needs in both residential and light-commercial settings.
