In the circuit breaker, the tripper and the operating mechanism 130 are correspondingly arranged through the armature, wherein the tripper is connected into the main circuit, when the main circuit is abnormal, the tripper can generate a large magnetic force to adsorb the armature, so that the armature moves to drive the lock catch of the operating mechanism 130 to trip, and further the movable contact 140 can be disconnected from the fixed contact 150, so that the main circuit into which the movable contact 140 and the fixed contact 150 are connected is disconnected, and an automatic disconnection function when the main circuit is abnormal is realized.

When the shunt 160 is connected to the movable contact 140, the shunt 160 may be connected to the second connection terminal 180.

And, can also combine communication module and control circuit to realize the remote control of circuit breaker.

Accordingly, it is possible to facilitate a user to detect and process a signal of the control circuit controlling the driving device 191 through the control signal interface by providing the control signal interface as one of the signal terminal interfaces 110 to be connected to the driving device 191. For example, the control signal interface is connected to two electrodes (a positive electrode and a negative electrode) of the driving device 191, and can detect a voltage signal (a positive bias voltage or a negative bias voltage) input by the control circuit to the driving device 191, thereby determining whether the control circuit controls the driving device 191 to rotate forward or backward, and the like.

For example, as shown in fig. 4, the signal terminal interface 110 may adopt a female interface structure to connect with an external signal processing device having a male plug. Or a male interface structure is adopted to be connected with an external signal processing device with a female interface.

Specifically, as shown in fig. 5, the signal terminal interface 110 may adopt a gold finger interface structure to connect with an external signal processing device having a corresponding gold finger interface.

Alternatively, as shown in fig. 4, when the signal terminal interface 110 includes a plurality of signal terminal interfaces 110, the plurality of signal terminal interfaces 110 are arranged in an array.

The plurality of signal terminal interfaces 110 are arranged in an array, so that the lines connected to the interfaces can be arranged more conveniently, and the space of the shell 120 occupied by the signal terminal interfaces 110 can be saved.

Alternatively, as shown in fig. 3, the circuit correspondingly disposed on each signal terminal interface 110 is integrated on the circuit board 111.
