The WDU 4 is a feed-through terminal block for DIN rail mounting in electrical panels and control cabinets. It accepts conductors up to 4mm² via a screw-type connection and is made from beige Wemid thermoplastic — the standard colour for the WDU 4 range and the conventional choice for general-purpose panel installations.

The terminal meets IEC 60947-7-1, the international standard for low-voltage switchgear and controlgear terminal block assemblies.
