The WDU 4 BL is a feed-through terminal block designed for DIN rail mounting in electrical panels and control cabinets. It accepts conductors up to 4mm² via a screw-type connection and is housed in blue Wemid thermoplastic, differentiating it from the standard beige WDU 4 in panels with mixed terminal types.

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