Product Overview

Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home's electrical system. To provide additional protection Siemens offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and Voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current.

Customer Questions & Answers

The description indicates this item is only compatible with 14ga wire. If this was a 15A breaker ...

The description indicates this item is only compatible with 14ga wire. If this was a 15A breaker that would make sense. However, if you are worried about sizing a circuit to the extent that you are using a 20A breaker, you should also be using 12 ga wire, which this device does not appear to allow. What item do you offer that will allow the use of 12ga wire?
Asked by: 1PickyElectrician
Hey, TomB! I am and have been a very experience electrician for nearly thirty years. Just like a lawyer, I knew the answer to the question before I asked it. However, I am also a very experienced Construction Manager and have been self employed for nearly forty years. Due to my experience, I knew my original post was the fastest way to have the description corrected. My thanks to the nice folks at Siemens, for their rapid response.

Is this part interchangeable with a Q120AFC?

Asked by: Dcw
Yes, this product will interchange with the Q120AFC, but if arc fault protection is required you will be creating a code violation.
