Terminal block
A terminal strip (also called a terminal strip ) is used in control cabinets to connect cables and lines. It is the interface between the control cabinet and the outside world, but it can also be used internally for the purpose of potential distribution. In the control cabinet, the terminal strip is usually arranged near the cable entry .
A terminal strip consists of individual terminal blocks that are mounted and lined up on a mounting rail (top hat rail). Mounting on the mounting rail distinguishes them from unattached terminals such as luster terminals . The terminal strip has its own equipment identification in the circuit diagram , usually with the code letter X and appears in the cable plan or wiring diagram.
Terminal strips with a soldering lug were also used, with which a cable provided with a cable lug could be connected to a soldered cable.
In Austrian hardware stores, the term terminal strip is often used for luster terminals.
