Description: Electromechanical safety devices that interrupt a circuit when the current through it goes beyond the nominal value. Can be reset manually after tripping and reused many times. Circuit breakers for DC have a different construction than those for AC (DC and AC electric arcs are extinguished differently), so choose your type accordingly.
