If you find one, let me know. I did some research a while back and found a list on Siemens web site of what panels their breakers were listed for. I included GE. The next week we failed an inspection for a Siemens breaker in a GE panel. The inspector was very insistent that no breakers were ever listed to be in other panels and wouldn't listen to me. I was going to print the web page for him, but it wasn't worth the effort, I just changed the breaker.
