Great replacement and good price.
The breaker fit my electrical box well and replaced a faulty breaker. The breaker was an easy install but make sure to turn off power to box!

Exactly as it says it is.
It’s a breaker , it works, great retro fit in an older home. Trips when it should and easily resets.

Typical of all Siemens High Quality Products
I purchased this breaker for my very humid greenhouse. I wanted to replace the non-GFI breaker in the greenhouse panel. I am a huge fan of Siemens electrical components and was pleased that the breaker fit my off-brand panel perfectly. The breaker is typical of all Siemens high quality products, good value for the money and it doesn't trip unnecessarily. Of course, a breeze to install - just remember to turn off all power to the panel before removing the cover.
