QBA222251 - 225 Amp Circuit Breaker

QBA222251 - 225 Amp Circuit Breaker

If you’re maintaining or servicing an existing PowerPact Q-Frame system, the QBA222251 is built for straightforward, form-fit-function compatibility. This 225 amp, 2-pole molded case circuit breaker is rated 10kA at 240VAC and is designed for I-Line, plug-on installation. It’s commonly used in commercial and industrial panelboards where matching the original frame type, phase configuration, and interrupting capacity matters. With a thermal magnetic trip unit, it provides both overload and short-circuit protection in one compact device. Like other breakers in the QBA series, it’s built to last and intended to perform consistently within its rated application.

Rather than changing system design, this breaker is meant to align with existing Q-Frame assemblies. The A-B phase configuration and plug-on I-Line mounting help ensure it seats correctly in compatible equipment, keeping your distribution setup operating as designed.

Key Features and Benefits

• 225 Amp Rating – Suitable for higher-load branch or feeder circuits in 240VAC systems.
