I have ordered several of these circuit breakers to use with my Siemens panel and still no problems. As a precaution for all DIY enthusiasts, it is NOT recommended to use 'compatible' (in the case of QT, Murray breakers) in place of OEM breakers. Siemens makes several claims in their installation manuals that the use of third-party circuit breakers can void panel warranties, and I've read online separate statements from homeowners that say panels can be marked during home inspection using switches from various manufacturers . and cause problems in the sale of real estate. Do yourself and your wallet a favor and buy switches from Siemens.
