The invention discloses a protection device having a short message sending function for an operating mechanism of a circuit breaker. The protection device comprises a current signal detection circuit, a detection signal processing circuit, a protection execution unit circuit, a state display circuit, a protection counting circuit and a short message sending circuit, wherein the current signal detection circuit is used for sending a detected current signal to the detection signal processing circuit for comparison, amplification, delay driving and RS triggering and then outputting a protection control signal, controlling the protection execution unit circuit to cut off a switching-off or switching-on power source of the circuit breaker, displaying a fault state is displayed, and counting, and meanwhile, the short message sending circuit is controlled by the counting circuit to send a short message of a protection action situation to a maintainer for timely maintenance. By the protection device, the situations o
