It is an electrical fault arc protector that can protect electrical appliances by cutting off power before a short circuit occurs，Arcs are visible plasma discharges caused by electrical current passing through a normally nonconductive medium, such as air. This is caused when the electrical current ionizes gases in the air, temperatures created by arcing can exceed 6000 °C. These temperatures are sufficient to start a fire.
