QOB245 - 45Amp Circuit Breaker

QOB245 - 45Amp Circuit Breaker

The QOB245 is a 45-amp, 2-pole bolt-on circuit breaker made for use in compatible 120/240VAC electrical systems. It protects branch circuits by interrupting power when an overload or short circuit occurs, helping reduce the chance of damage to wiring and connected equipment. Its bolt-on design provides a secure connection to the panelboard, making it a common choice in commercial buildings, industrial facilities, and many residential applications. If you're replacing an existing breaker, matching the correct amperage, pole configuration, and breaker type is essential for proper operation. The QOB245 offers a 10kA interrupting rating at 120/240VAC and is suitable for applications that require a Type QOB bolt-on breaker. Simple, dependable circuit protection is exactly what this breaker is intended to provide. It's a practical option for panel maintenance, equipment upgrades, and electrical repairs where compatibility with a Type QOB system is required.
