Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your homes 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.
