DFW-3 Series Cable Branch Box (US)

Introduction


DFW series American Style Cable Distribution Box, with one-way door opening and horizontal multi-pass busbar as its main characteristics, has the advantages of small width, flexible combination, full insulation, full sealing, good performance, standard design, beautiful appearance, etc. It is widely used in cable engineering equipment in the cable distribution network system. According to the rated current, the DFW series cable junction box can be divided into 600A main circuit type and 200A branch circuit type: the 600A main circuit type adopts screw-in bolt fixed connection; the 200A branch circuit type adopts plug-in connection and can be plugged and unplugged with load. The DFW series have been widely recognized in various places such as industrial parks, residential quarters, urban densely populated areas, commercial centers and high-rise buildings.
