The utility model discloses a circuit breaker suppressing motor fault processing device which comprises a left operation plate and a right operation plate. The left operation plate and the right operation plate are connected together through a bolt hole, a bolt rod and a compression spring which sleeves the bolt rod. Both ends of the compression spring are respectively fixed on the inner side walls of the left operation plate and the right operation plate. Three bus pieces are fixedly arranged on the inner side wall of the right operation plate. A handle is fixedly arranged on the outer side wall. Three bus piece holes are arranged in the left operation plate. The positions of three bus pieces and three bus piece holes match three phases of contact of a contactor. Spacing clamping plates are arranged on upper and lower ends of the left operation plate. According to the utility model, in the emergency situations of abnormal pressure, continuously reduced pressure and the like, three phases of contact of the contactor are forcibly switched on; an energy storage motor timely starts to carry out suppressing; a normal pressure value and normal breaking ability of a circuit breaker pneumatic mechanism are recovered; an accident range can be reduced as much as possible; the workload of switching operation is effectively reduced; and the time of handling abnormalities can be greatly shortened.
