QOB3301021 - 30A Circuit Breaker w/ 120V Shunt Description
QOB3301021 - 30A Circuit Breaker w/ 120V Shunt
The QOB3301021 is a 3-pole, 30-amp bolt-on circuit breaker designed for dependable circuit protection in commercial and industrial panelboards using a QOB frame type. Rated at 10kA interrupting capacity at 240VAC, this breaker is built to provide safe, code-aligned overcurrent protection while maintaining proper form, fit, and function in compatible electrical distribution systems. Equipped with a factory-installed 120VAC shunt trip device, the QOB3301021 allows for remote tripping capability—making it suitable for applications that require emergency shutdown or automated control integration. Built to last and engineered for consistent operation, this bolt-on breaker helps maintain system integrity in existing installations where QOB-series devices are specified.
