QOB2301021 - 30Amp Circuit Breaker

QOB2301021 - 30Amp Circuit Breaker

The QOB2301021 is a 2-pole, 30-amp bolt-on circuit breaker designed for use in compatible Type QOB panelboards. It provides overcurrent protection for 120/240VAC branch circuits and includes a 120VAC shunt-trip device, allowing the breaker to be tripped remotely via an external control circuit. A bolt-on mounting design helps keep the breaker securely fastened inside the panelboard, making it a common choice for commercial and industrial electrical systems. The built-in shunt trip is often used when a breaker needs to open on a remote signal, such as in fire alarm systems, emergency stop stations, or building controls. With a 10 kA interrupting rating at 120/240 VAC, this breaker is suitable for many standard electrical distribution applications. Whether you're replacing an existing breaker or maintaining a compatible panel, the QOB2301021 provides the electrical protection and remote-trip capability required for many everyday installations.
