Description
Finding reliable replacements for older electrical systems requires exact matches. This 15A, single-pole miniature breaker fits the classic XO frame footprint, delivering thermal-magnetic protection for standard 120VAC residential branch circuits. Compatibility remains strictly limited to original Square D and Cutler-Hammer XO series panelboards. The plug-on mounting style ensures a secure connection without modifying the existing busbar infrastructure.Specifications

Product FAQs
7 answersWhich electrical panels accept the Square D XO115?
This breaker is strictly compatible with vintage Square D XO and Cutler-Hammer XO load centers. It will not fit in modern Square D QO, Homeline, or Cutler-Hammer CH or BR panels.
Can the Square D XO115 replace Cutler-Hammer XO breakers?
Yes. Because Cutler-Hammer and Square D shared the XO frame design in older panels, this breaker serves as a direct drop-in replacement for 15-amp, single-pole Cutler-Hammer XO breakers.
How is the XO115 installed into the load center?
It uses a standard plug-on connection that snaps directly onto the panel busbar. No mounting screws or modifications to the existing busbar infrastructure are required.
What wire gauge is required for the XO115 terminals?
The screw and clamp terminals accommodate wiring between 14 AWG and 10 AWG, which is standard for 15-amp branch circuits.
What type of circuit protection does the XO115 provide?
It features a fixed thermal-magnetic trip mechanism. The thermal element responds to prolonged overloads, while the instantaneous magnetic element trips immediately during short circuits.
Is the XO breaker series still used in new construction?
No, the XO frame is a legacy design that has been obsolete for decades. The XO115 is intended exclusively as a replacement component to maintain existing older electrical infrastructure.
Is the 10kAIC interrupting rating sufficient for residential use?
Yes, a 10kAIC rating at 120V is the standard fault current rating for most residential branch circuits where these legacy XO panels are typically installed.

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.
