Weidmüller WDU 2.5N (Order No. 1023700000) is a dark beige feed-through terminal block rated at 2.5 mm² cross-section, 24 A, and 500 V, certified to IECEx/ATEX for 352 V / 24 A (Ex eb II C Gb, II 2 G D). It offers 2 connections across 1 level with 2 clamping points per level via screwable cross-connection, and requires an end cover plate. Mounted on a TS 35 rail, it measures 5.1 x 44 x 37 mm (W x H x D), weighs 5.34 g, and has a rated impulse withstand voltage of 6 kV.
Feed-through terminal blocks are suited to joining and/or connecting one or more conductors carrying power, signal, or data, with one or more connection levels that can share a potential or be insulated from one another — the insulating material, connection system, and design are what differentiate individual terminal block types. This model is made from Wemid material with a UL 94 V-0 flammability rating and is RoHS compliant.
