Here, the Pan Assambly busbar is used to save space in tight applications. Also, the feed is not done from below but above the pins of the busbar. However, 40 mm, 100 mm and 185 mm systems are also in use. Notable cost reduction compared to conventional installation in switchgear and control cabinets due to the following reasons: Mechanical fixing and electrical contacting in a single step No access. A busbar is a metallic conductor used to distribute electrical power efficiently within electrical panels, switchboards, and industrial power systems. A busbar is defined as an electrically conductive strip or bar used to distribute power to multiple circuits in parallel. The double-pole Auxigaine busbars are suitable for superstructures up to 1. 90m in length. ABB busbar systems enable safe and easy cross-wiring of miniature circuit breakers, residual current devices and other Modular DIN-Rail products. The following points should be considered when selecting the correct busbars: REG terminal type (twin terminal or cage terminal), number of poles, device. Flexible and solid busbars made of copper, aluminum or CoppAl® serve as the central distribution board in your switchgear.
