Data sheet Weidmller Interface GmbH & Co. KG ZDU 4/4AN Klingenbergstrae 26 D-32758 Detmold Germany www.weidmueller.com Product image To feed through power, signal, and data is the classical requirement in electrical engineering and panel building. The insulating material, the connection system and the design of the terminal blocks are the differentiating features. A feed-through terminal block is suitable for joining and/or connecting one or more conductors. They could have one or more connection levels that are on the same potential or insulated against one another.
