QOB220 - 20 Amp Circuit Breaker

QOB220 - 20 Amp Circuit Breaker

The Square D QOB220 is a 20 Amp, 2-pole bolt-on circuit breaker built for use in compatible QOB panelboards operating on 120/240VAC systems. Whether you're replacing a worn breaker or maintaining an existing electrical panel, the QOB220 delivers the overcurrent and short-circuit protection needed to help keep your electrical system operating safely. Its bolt-on mounting design creates a secure connection to the panel, making it a popular choice for commercial and industrial applications where vibration or frequent service can make a solid mounting method especially important. With a 10kA interrupting rating, this breaker is suitable for many standard branch circuit applications requiring dependable circuit protection. Before installation, always verify that the breaker's type, amp rating, voltage rating, and mounting style match the requirements of your panel and electrical system.
