DFW American Type Cable Branch Box is designed for medium voltage cable distribution networks. Featuring single-side access, horizontal busbar design, full insulation, and sealed structure, it supports 600A main circuits and 200A load-break branch circuits for flexible, safe, and reliable power distribution.
The DFW American Type Cable Branch Box is widely used in cable distribution networks thanks to its excellent performance, standardized design, and attractive appearance.
It has been extensively applied and recognized in industrial parks, residential communities, densely populated urban areas, commercial centers, and high-rise buildings.
This product features single-side access doors and a horizontal busbar connection design, offering advantages such as compact width, flexible configuration, full insulation, and full sealing.
According to rated current, the system is generally divided into 600A main circuits and 200A branch circuits:
• 600A main circuits use screw-in bolt-fixed connections
• 200A branch circuits use plug-in connectors and support load break insertion and withdrawal
