They integrate a variety of electrical components, including circuit breakers, fuses, and switches, ensuring the safe and stable distribution of electrical energy to various devices. Distribution cabinets not only effectively prevent abnormalities such as circuit overloads and short circuits, but also provide energy metering and quality control functions, providing strong support for the stable operation of power systems. Widely used in buildings, factories, shopping malls, and other locations with high electricity demands, distribution cabinets are essential for ensuring the safe and stable operation of electrical equipment and circuits.

[0003] The controller on the distribution cabinet generally consists of a controller body and a control panel. The control panel is located outside the cabinet door.
