QOB120VH1021 - 20Amp Circuit Breaker

QOB120VH1021 - 20Amp Circuit Breaker

Some applications need more than a standard circuit breaker. If your system requires the ability to shut off power remotely, the QOB120VH1021 adds that extra layer of control with a factory-installed 120VAC shunt trip device. When a remote signal is received, the breaker trips automatically, making it a practical choice for systems tied into emergency stops, fire alarms, security controls, or building automation. Rated at 20 amps with a 22kA interrupting capacity at 120/240VAC, this single-pole QOB-VH breaker is built for dependable branch circuit protection in commercial and industrial electrical systems. The bolt-on design provides a secure fit in compatible panelboards, helping reduce movement and maintain a solid electrical connection over time. For electricians, maintenance teams, and facility managers, reliability is just as important as the specifications. That's why this breaker is commonly selected for installations where dependable overcurrent protection and remote trip capability need to work together. Whether you're replacing an existing unit or completing a new installation, the QOB120VH1021 delivers the performance expected in demanding electrical environments.
