QAF is an AFCI breaker.

QAF2 is an AFCI/GFCI breaker.

QAF is an AFCI breaker.

QAF2 is an AFCI/GFCI breaker.

So a QAF2 breaker would meet the GFCI requirements for a dishwasher in a dwelling?

I believe I made an oops.

QAF2 is simply a Combination-type AFCI breaker.


They do have AFCI/GFCI combo breakers of types: QFGA2/QFGAH2/HQFGA2

I have AFCI breakers that are QAF type and they also say combination type.

As best I can tell, the -2 model uses "New and improved electronics" among a couple other enhancements...

Dual function is the term we should use, its what Sq D uses. A combination AFCI is the type required effective Jan 1, 2008 that replaced the branch circuit feeder type.

Siemens uses that term also... for the AFCI/GFCI combo breakers. The QAF and QAF2 are not.
