Answer: 
Square D QO loadcenters are not approved for DC applications and a QO circuit breaker would have to be installed in a QO loadcenter. A better solution would be to protect a 12 volt DC circuit with a fuse.

Answer: 
No, Square D QO circuit breakers can only be used in Square D panels. Murray panels need Murray circuit breakers and Siemens panels need Siemens circuit breakers, The only exceptions are if other manufacturer's circuit breakers are listed on the label inside the door. Square D QO circuit breakers are not even physically interchangeable with Murray and Siemens circuit breakers.
