The utility model discloses a surface contact plug-in type breaker, and belongs to the technical field of circuit safety protection. The surface contact plug-in type breaker comprises a breaker body and a plug-in type mounting table. The breaker body also comprises a plug which is a planar structure. The plug is fixedly arranged on a wiring terminal of the breaker body and reliably contacted. The plug-in type mounting table comprises an insulation bench, a socket, a compaction bolt and a locking bolt. A socket of plug-in type back-panel wiring is an L-shaped bending structure. Through holes are processed on a horizontal part and a vertical part of the socket. An external surface of the vertical part of the socket is a contact surface of the plug. A head of the compaction bolt is arranged fixedly in the insulation bench. After the screw part of the compaction bolt passes through the through holes arranged on the insulation bench and the vertical part of the socket, the screw part is exposed for electrical connection of the breaker body and the plug-in type mounting table. A head part of the locking bolt is arranged fixedly in the insulation bench. After the screw part of the locking bolt passes through the insulation bench, the screw part is exposed for plug-in type connection with the breaker body. According to the plug-in type breaker provided by the utility model, security problems in the traditional plug-in type wiring structure caused by contact heating under heavy current are solved.
