Review on ⚡ Siemens Q120DF Circuit Breaker: Enhanced Functionality for Effective Performance by Mike Lawler

Siemens Q120DF 20-Amp I got this to add a stack circuit to my panel where I wanted it and GFCI protection class A , and CAFCI protection (AFCI required, GFCI was optional by code). After reading a lot about AFCI in general (nothing special about the Siemens brand), I was worried about nasty triggers. Did I mention AFCI is now required by code? I had my main panel replaced a few years ago to rewire my house. I chose the Siemens panel mainly because of the availability of these switches at the time and the relatively few complaints about Siemens equipment. So far so good, this circuit breaker is installed and have been in use for about 2 weeks and I am using a Dyson vacuum, my desktop computer and various equipment, a Dremel Multi-Max, a shop vacuum. , room light and a few other articles from this thread, and there was no travel. I'll update if anything happens, but overall I'm happy. Best of all, it was (back then) only $10 more than a CAFCI switch, add a quality GFCI outlet and you pay about the same. If you enjoy working with electricity, great, if not then hire a professional. Update April 2019 Still no issues with this switch and I've added more. It worked because one of our built-in lamps intermittently arced onto the case. Finding the problem was a frustrating exercise. I can still recommend her even after 4 years.
