A set of bars is a crucial part of any efficient electrical power distribution system that allows for greater flexibility and reduced overall installation costs. The BusBar Box allows this facility to be implemented in hazardous areas, often to provide a temporary electrical connection during the construction and commissioning phases. Made of 316L stainless steel (1.404), rated IP66 and type 4X, the BusBar Box case is comfortable in any exposed marine or terrestrial environment. In addition to the use of shoulder presses, cable integration can also be achieved via modular transit systems, while maintaining IP and Ex classifications. Several protective paints and assembly frames are available to meet the specific needs of a project.
