The Square D QO230 is a plug-in breaker from the QO series, designed to install in Square D QO loadcentres and panelboards — the industry's most widely used residential panel line in Canada. It occupies 2 pole spaces and is rated 30A / 120/240V / 10kA AIC, making it suitable for branch circuits such as dryers, ranges, water heaters, and sub-panels in residential and light commercial settings.
The QO plug-in design is not interchangeable with Square D Homeline, Siemens, Eaton, or other brands' loadcentres. Have a QO panel and want to be sure? Send us your panel model number and we'll confirm fitment.
No — QO and Homeline breakers use different bus designs and are not interchangeable. The QO230 is designed exclusively for Square D QO loadcentres and panelboards. If you're unsure which series your panel is, send us the model number from your panel's label and we'll point you to the correct breaker.
The QO230 is a 2-pole 30A 240V breaker commonly used to protect dedicated branch circuits for electric dryers (typically 30A), water heaters, well pumps, and similar double-pole 240V loads. Always verify the load's required amperage and wire gauge (typically 10 AWG for 30A circuits) against Canadian Electrical Code requirements before installation.
