The new space-saving WDK 2.5 DU PE TR series enables you to wire up signal circuits using only one terminal block. The signal can be fed through the upper level of the terminal block so that the lower connection level still has room for the neutral conductor. The accompanying shield connection can save space by connecting to the integrated PE connection. This means that additional PE terminal blocks or other connection mechanisms in the electrical cabinet are no longer required. Depending on the type of signal and requirement, the upper connection level can be fitted with a disconnect lever or pluggable SIHA safety lever. The WDK 2.5 DU PE TR – with a width of only 5.1 mm – currently offers the highest wiring density of all screw terminal blocks for signal routing, and it does this without compromising on versatility or functionality.
