## Description

Product Description 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. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so.

## Questions & Answers

**Q: My welder is a 240v don’t know what breaker circuit I need to upgrade**
A: -1st.- What is the make of the panel
-2nd- How many amps does the welder need, is should be written on a plate stuck to the welder
-3rd- then you purchase the good brand, 240V - ???Amps

**Q: Will this breaker fit in a br panel???**
A: Please contact the manufacturer of the panel to see what breakers are listed for use.  While our breakers might fit, we don't test for use in other manufacturer equipment.

**Q: Can i use this q115 15-amp single pole type qp circuit breaker to replace a crouse hinds circuit breaker. wasnt sure ?**
A: It will certainly fit and work, but it is not approved. You need to use the breakers listed on the inside door of your crouse-hinds panel. I went through the same thing. I just bought used Bryant BR/BD breakers on ebay. Cost is a little more, but ironclad for insurance and code reasons.

**Q: Where does Amazon get the Seimens breakers  supplied and shipping by Amazon?**
A: I’m not sure I’ve ordered a couple of them and first time it took 3 days to come in and the second time it took 2 days
