This breaker wasn’t available at my local hardware, but I found it in another location and it was twice as much, so very good value.Works just fineWorks as it should , that brand is hard to find around where I liveHad to use a couple of 15amp peanut breakers to put this 30 amp breaker in for a new 240 volt heater that was being installed in my garage. It was a tight fit but works great.Wanted to hook the generator into the fuse box to eliminate a bunch of extension cords.It's a breaker, fits my Siemens panel and therefore does not void the warranty. I've exclusively used Siemens breakers for years, none better in my opinion.
