However, as an electrical device, the device contains electronic components, coils and other components that are easy to heat up. Therefore, in order to ensure the normal operation of the circuit breaker and extend its service life, it is usually necessary to properly dissipate heat. The main purpose of heat dissipation is to prevent the circuit breaker from being damaged or malfunctioning due to overheating. Overheating may cause failure of electronic components and poor contact inside the circuit breaker, thereby affecting the performance and reliability of the circuit breaker. After the device cuts off the circuit, it cannot make a sound to remind the staff in time which line is faulty. Utility Model Content

The setting of the holder 10 is used to fix the alarm 4.

An electrode sheet 13 is fixedly connected to one end of the battery slot 11 away from the battery spring 12. The electrode sheet 13 and the battery spring 12 play a conductive role. A slot 14 is fixedly opened at one side of the bottom end of the circuit breaker body 1, and a slide plate 15 is slidably connected inside the slot 14. The setting of the slide groove is used for the slide plate 15 to slide in the slot 14.

[0036] See also Figure 2 , Figure 3 and Figure 5 A paddle 16 is fixedly connected to one side of the slide plate 15, and the paddle 16 is used to facilitate fixing the paddle 16.

[0037] In this embodiment, the intelligent molded case circuit breaker can be used in the operation of the device through the arrangement of the heat dissipation grooves 6 and the fan 9. Since the intelligent module 5 contains electronic components, coils and other components that are easy to generate heat, a plurality of heat dissipation grooves 6 are opened on one side of the intelligent module 5 of the circuit breaker, and the fan 9 is arranged to blow air to the intelligent module 5 to dissipate the heat generated by the intelligent module 5, so that the intelligent module 5 in the circuit breaker maintains a suitable working temperature.

[0038] It should be noted that the battery 18 is a detachable structure and can be replaced when the battery 18 is out of power.

[0039] The working principle of the above embodiment is:

[0040] When the circuit breaker is in normal working condition, the intelligent module 5 continuously monitors the state of the circuit. At the same time, the fan 9 is also working, providing continuous heat dissipation for the intelligent module 5 through the heat dissipation slot 6 to ensure that the intelligent module 5 is at a suitable working temperature. When a fault occurs in the circuit, the intelligent module 5 will quickly detect these faults. Once the intelligent module 5 detects a circuit fault, it will immediately trigger the circuit breaker body 1 to act and cut off the faulty circuit to prevent the fault from expanding or causing damage to the equipment. When the circuit breaker is actuated, the alarm 4 connected to the circuit breaker will also be activated. After the alarm 4 receives the action signal of the circuit breaker through the wire 3, it will emit sound and light to alert the staff and indicate which line has a fault. After hearing the alarm, the staff will quickly go to the scene, find the faulty line according to the instructions of the alarm 4, and take corresponding measures.
