The waist holes on the left and right sides of the mounting rails A803 and B804 correspond to the waist holes on the left and right fixing strips 802, respectively.

[0031] The two fixing strips 802 are provided with multiple waist holes. The mounting rails A803 and B804, as well as the wire trough mounting rail 801, can be adjusted at any time according to actual needs. Through this modular design, electrical components can be flexibly installed on different rails according to actual needs, which greatly improves the flexibility and convenience of installation.

[0032] In summary, this modular distribution box facilitates the installation of electrical components through the installation module 8. The fixing strips 802 on both sides have multiple slots, and the mounting rails A803, B804, and cable tray mounting rail 801 can be adjusted as needed. This modular design allows electrical components to be flexibly installed on different rails according to actual requirements, greatly improving installation flexibility and convenience. Furthermore, the stainless steel frame 7 and stainless steel door 10 are both made of transparent plastic, allowing staff to directly observe the internal electrical components through these transparent viewing windows. The working status of the components can be detected in time without opening the electrical box cover 5, which improves maintenance efficiency. When it is necessary to operate the internal switches, simply flip up the stainless steel door 10 for quick and easy operation. This modular distribution box, through the design of combining heat dissipation holes 2 with exhaust fans 11, forms a good air convection channel, thereby effectively reducing the internal temperature of the electrical box, ensuring that the electrical components work in a suitable temperature environment, and extending their service life. The top cover 4 is wider than the electrical box and has an inclined front end, which can effectively block dust and debris, prevent them from accumulating on the heat dissipation holes 2 and electrical components, and ensure the stability of heat dissipation.
