[0002] A low - voltage circuit breaker is also called an automatic air switch, simply referred to as a circuit breaker. It integrates control and multiple protection functions. When the line is working normally, it acts as a power switch to connect or disconnect the circuit; when faults such as short - circuit, overload, and undervoltage occur in the circuit, it can automatically trip and cut off the faulty circuit, thereby protecting the line and electrical equipment. It is an extremely important protection and control device for the line.

[0003] As disclosed in the patent with the authorization announcement number CN218040243U, a low - voltage power distribution protection and control device is disclosed, including a low - voltage power distribution protection and control main body.

Through holes are respectively provided on the left and right side surfaces of the housing. Dehumidification components are respectively provided at the left and right ends inside the housing at the positions of the through holes. The dehumidification component includes a rectangular frame, a dehumidifying member for removing water vapor inside the housing, a heating member for heating and evaporating the water on the dehumidifying member, and a negative - pressure member for discharging the heat inside the rectangular frame. Through the setting of the dehumidification component in the housing, the dehumidifying member can adsorb the moisture in the air near the through holes and inside the housing to achieve the purpose of dehumidification. In addition, when it is necessary to dehumidify the dehumidifying member itself, through the operation of the heating member, the moisture in the dehumidifying member can be heated and volatilized, and discharged to the outside of the housing through the negative - pressure member, so as to achieve the cyclic use of the dehumidifying member.
