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. From the Manufacturer Siemens plug in circuit breakers are intended for use in Siemens EQ, Siemens Ultimate, ITE, and Gould load centers or meter combinations. The single pole Siemens breakers may be used in single or 3-phase load centers and are 120V rated. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required.

  • Original equipment for my panel. Works great.
Size: 15 Amp Style: 1 Pack
Years ago I worked doing some electrical work. Recently I had a breaker at my home that was acting flaky, so wanted to replace it. I called an elecrical contractor (who installed my Generac), and he quoted me $225 to come out and replace it. That did not include the cost of the breaker itself. *** If you have not worked with breaker boxes, note that there are LETHAL voltages in there **** if you touch the wrong thing, you can kill yourself ***** (It took ten minutes and < $10) ... show more
