Specifically designed for heavy load DC switching
These Circuit Breakers and contactors specifically designed to break DC are available for commercial applications. Unlike an AC breaker, DC Breakers are designed to reduce the impact of arc activity common to switching DC voltages. A number of schemes often used in combination act to increase the chutes, which force the arc to take a convoluted path, and also cool or quench it. In another technique, magnetic blowout , the arc traverses a magnetic field. This imposes a force perpendicular to the path of the arc, blowing it sideways, and stretching it. The third technique is to form the arc in a vacuum or hydrogen, or other atmosphere which does not favor arcing.
