Summary:The invention discloses a control circuit of a circuit breaker and the circuit breaker and relates to the technical field of circuit breakers. The control circuit of the circuit breaker comprises a first terminal and a second terminal with opposite polarities, a first change-over switch, a second change-over switch, a bridge rectifier circuit and an actuating mechanism. A first input end and a second input end of the bridge rectifier circuit are electrically connected with the first terminal and the second terminal correspondingly, and an output end of the bridge rectifier circuit is electrically connected with the actuating mechanism. The first change-over switch and the second change-over switch are connected between the first terminal and the first input end in parallel, and a normally-closed contact and a normally-open contact of the first change-over switch are electrically connected with the first input end. A normally open contact of the second change-over switch is electricallyconnected with the first
