I. Overview:

American style cable distribution boxes, with their excellent performance, standardized design, and beautiful appearance, are widely used as cable engineering equipment in cable distribution network systems. They are widely recognized in various places such as industrial parks, residential areas, densely populated urban areas, commercial centers, and high-rise buildings. It is mainly characterized by one-way door opening and horizontal multi-channel busbar, with significant advantages such as small width, flexible combination, full insulation, and full sealing. According to the rated current, it can generally be divided into two types: 600A main circuit and 200A branch circuit. The 600A main circuit adopts a screw in bolt fixed connection, while the 200A branch circuit adopts a plug-in connection and can be plugged and unplugged with load.
