ZDU 2.5/3AN RT Weidmüller Interface GmbH & Co. KG Klingenbergstraße 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 fea- tures. 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. General ordering data Version Feed-through terminal, Tension-clamp connection, 2.5 mm², 800 V, 24 A, red Order No. 1683340000 Type ZDU 2.5/3AN RT GTIN (EAN) 4008190477981 Qty. 100 items Creation date 27.02.2026 11:58:34 MEZ Catalogue status / Drawings 1
