The UTTB 4 connects conductor crosssection ranges of 0.14 to 4 mm2 and the UTTB 2.5 connects ones of 0.14 to 2.5 mm2. A universal FBS plug-in bridge system allows cross connections to neighboring feedthrough terminal blocks. And bridging from the upper level to the lower level can be accomplished with a special FBS component.
