Built to restore functionality in older homes, the Square D XO1215 is a 15-amp, two-pole miniature circuit breaker. It delivers reliable thermal-magnetic protection for 240V residential applications. This component serves as an exact replacement for aging hardware, snapping securely into legacy Square D and Cutler-Hammer XO panelboards. It utilizes a standard plug-on mounting style for simple panel integration.

Product FAQs
5 answers
Which electrical panels accept the XO1215 breaker?
This plug-in breaker is compatible with legacy Square D XO load centers as well as Cutler-Hammer XO load centers.
Can this Square D breaker replace a Cutler-Hammer XO breaker?
Yes. Because Cutler-Hammer and Square D both manufactured the XO series, the XO1215 serves as a direct replacement for 15-amp, 2-pole Cutler-Hammer XO breakers.
What wire sizes are compatible with the XO1215 terminals?
The screw and clamp terminals on this breaker accommodate wiring ranging from 14 AWG to 8 AWG.
How does the thermal-magnetic trip mechanism function on this breaker?
It provides dual-level protection: a thermal element responds to prolonged overloads (long-time trip), while a magnetic element reacts immediately to severe short circuits (instantaneous trip).
Is the XO breaker series still manufactured for new installations?
No, the XO frame is a legacy design. These breakers are primarily sourced to maintain and service existing, older load centers rather than for new construction.

Square D xo15
I ordered 3 xo15 breakers from another company that advertised them as new and since they're obsolete breakers they were quit expensive however when i received them only one was new the other two were obviously used, corroded and missing the wire screw. SuperBreakers sent me New Breakers at a much better price. Happy customer

Everything went great from beginning to end. Breaker came next day and I had electricity again! Not to mention my breaker was an old obsolete model. They had it in stock. Saved me from replacing while breaker box.
