The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. As the complexity of the circuit increases, the use environment of the distribution box is gradually increasing. For the distribution box used in a humid environment, in order to increase its service life, it is necessary to set a dehumidification structure in it so that the components installed in it can reduce the corrosion rate.
