Abstract

Connecting bars are made from profiled semifinished products and have a cavity. The bars have the same outer dimensions for different nominal currents and are intended for connecting the electrical components of electrical devices and apparatus to an external electrical circuit. The connecting bars extend through the window opening located in the wall of the devices or apparatus and are fixed in the housing by a fixing device including two or more partial parts profiles. These are configured in such a way that they can be connected to one another by positive fit or otherwise to a hollow connecting bar. The partial parts have one or several legs, the length of which defines the height of the connecting bar.
