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.

Answer: 
Hi ken,
Several years ago Siemens purchased ITE. All of Siemens’ QP breakers can be retrofitted to fit an ITE panel. The QT breaker family could be retrofitted to the old ITE panel if you have an ITE panel that is designed to accept tandem circuit breakers, there should be a few spaces on the bus bar that are "notched" to accept tandems.

Answer: 
Hi jpf5005,
You can only place tandem circuit breakers in a panel that is designed to accept tandems. For example, a 12 space/24 circuit load center will have notched tabs that accept tandem circuit breakers at the bottom of the bus bar. A 20 space/20 circuit panel on the other hand will not accept tandems. Look at the wiring diagram inside your panel and it should list what breakers are compatible.

Answer: 
Hi Ruski915,
It is not recommended that you mix and match circuit breakers and place Siemens circuit breakers in other manufacturers panels. Siemens breakers are only UL listed to be used in Siemens panels.

Answer: 
Hi Japery,
It is not recommended that you mix and match circuit breakers with other manufacturers panels. Siemens circuit breakers are UL listed for use only in Siemens panels, using this product in any other manufacturers products will void all warranties.
