Hello forum, I’m working for a customer that has an old breaker style im not familiar with. My supplier said Square D type QO will fit but it doesn’t look the same to me.

If anyone know for sure what style will fit to replace them I’d appreciate it.

Thanks

If it has a tan handle, it’s an Eaton CH.
 
Definitely not a Square D QO. The QO foot and bus jaw has not been changed since they were introduced in the late 50's.

This looks like an old Cutler Hammer CH, which is the only brand I knew that had spring clips on the jaws.

Show us the front. There might be a UL label on the end above the load lug.
