The invention relates to a conductive structure for a parallel control breaker. The conductive structure comprises a connecting sheet (1), a thermal deforming irregular piece (2), an adjusting sheet (3), a moveable contact part (4), an elastic bracket (5), a position control component (6) and a wire (7). When the conductive structure is applied to the breaker, the conductive structure has a function of conducting the circuit; when the current in the circuit exceeds a rated current, the thermal deforming irregular piece thermally deforms, so that the conductive structure is separated from the outside current and the overload protection for the whole circuit can be achieved.
