Abstract: A bus bar holder having at least one bus bar receiver formed in a support element, with a width that can be varied for receiving bus bars of different cross sections by means of an adapter element, which can be plugged or locked in a holding structure with a matched and complementary holding structure in a bottom area. There are a variety of adaptations for adapting the bus bar receiver in the depth direction, because a separate spacer is provided, which can be removably attached on the bottom area of the bus bar receiver and which has a free space in the area of the holding structure, through which the holding structure is accessible for inserting the adapter element.

Abstract: A device adapter for pluggable connection to busbars of a busbar system with terminal connectors disposed in an oblong adapter housing and having catches for securing on a lower securing element and a section of a top hat rail for placing a device thereon. The adapter housing is divided into two halves in a longitudinal direction and parallel to an attachment direction. On their facing sides, the housing halves support securing elements distributed in the longitudinal direction over a separating plane, but offset in a step-like manner transversely thereto for securing, fixed against relative rotation, a plurality of U-shaped flat plug connectors, thereby enabling the pluggable connection. The housing halves are connected to each other and the U-shaped flat plug connectors are connected by conductors to terminal connectors housed in a contact block or directly to the device to be placed thereon.

Abstract: A busbar system with busbars fitted in a trough-like lower securing section extending over a length. A clamping arm perpendicular is secured to a securing surface of the lower securing section on which adapters fitted with terminals can be fitted and covered. The adapters can be secured to the lower securing section by mechanical catches. This invention improves mechanical securing of covers and adapters because the lower securing section has an outer wall and an inner wall longitudinally on both sides forming a longitudinal catch recess. The outer walls also have an outwardly directed longitudinal catch web, and retaining springs with catch webs of the side walls of the cover and adapter housing that run parallel to the busbars can be engaged in the longitudinal catch apertures and additional components securable to the adapter housing can engage with retaining springs on the outwardly directed longitudinal catch webs of the outer walls of the lower securing section as a tilting safeguard.
