Why this bolt-on breaker matters
The QOB230AS delivers dedicated protection for 240V, two-pole circuits in panels that support bolt-on breakers.

- Maintenance replacements in residential or light commercial panels that require the QOB family specifications.

- Use the part number QOB230AS as the primary reference to ensure exact compatibility with your Square D system.
