The QO315 – SQUARE D 3P15A 240V Push In Breaker is a reliable solution for your electrical needs. Designed for three-phase systems, this 15 Amp breaker ensures optimal circuit protection at 240V. Easy to install with a push-in design, it provides durable performance and enhances safety in your applications. Perfect for residential or commercial use.
The QO315 is designed for Square D QO loadcentres and panelboards that accept three-pole, plug-in QO-series breakers. It uses a proprietary plug-in bus connector and will not fit Homeline panels or other brands. Send us your panel model number and we'll confirm compatibility.
Yes — the QO315 is rated 3-pole, 15A, 240V with a 10kA interrupt rating, making it suitable for three-phase branch circuits in both residential and light-commercial QO panelboards. Always verify that your panel supports three-phase bussing, as not all QO loadcentres are configured for three-phase service.
Square D QO-series breakers are generally still part of the active product line, but specific configurations like the 3-pole 15A can sometimes be difficult to find locally. Northern Breaker Group specializes in hard-to-find and obsolete breakers — reach out to our Calgary, Edmonton, or Vancouver counters or request a quote online and we'll track it down for you.
