🔍 About the Product Transition: WAGO and Connexbox
Until recently, many of the grey electrical junction boxes associated with WAGO were actually manufactured by Connexbox, a UK-based specialist in enclosure design.
WAGO has now chosen to move in a new direction with its own in-house product — the WAGO Box PRO 207-3323. This junction box is not part of the previous grey box range and represents a new generation of official WAGO-branded enclosures.
✅ What You Should Know:
- The WAGO Box PRO is WAGO’s own current offering, specifically designed for 221 Series connectors
- It features a new design, distinct from the grey models previously distributed
- The original grey boxes are still available — now under the Connexbox name, with no change to build quality
