The QOB230EPD Square D 2P30A 120/240 Bolt-On Breaker offers reliable equipment protection for your electrical systems. Designed for two-pole applications, this 30-amp breaker ensures safe and efficient operation, preventing overloads and short circuits. Ideal for a variety of settings, it’s a perfect addition for both residential and commercial needs.
The QOB230EPD includes built-in Equipment Protection Device (EPD) functionality, which provides an additional layer of protection against ground faults that can damage motors, appliances, and other equipment — without the nuisance tripping of a standard GFCI breaker. A standard QOB230 offers only overload and short-circuit protection, with no equipment protection feature.
No — the QOB series uses a bolt-on bus connection, which is not compatible with the plug-on design of standard residential QO loadcentres. The QOB230EPD is intended for Square D QO bolt-on panelboards used in commercial and light-industrial applications. If you're unsure which style your panel accepts, send us the panel model number and we'll verify compatibility.
The QOB230EPD with EPD functionality can be difficult to source through standard supply channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers across our Calgary, Edmonton, and Vancouver locations. Contact us for a quote and we'll check current availability for you.
