WAGO 221 terminal block with 10 connections for space-saving wiring WAGO 221 terminal block with 10 connections for space-saving wiring

The 221 Series Expands

Now with 10 Connection Points!

May 14,, 2025

The proven connection technology of the 221 Series just got even more versatile: a new double-deck terminal block with ten connection points is now available. Thanks to the lever technology, wiring remains as simple as ever: Lever up — insert conductor — lever down — done!

With this new terminal block, installers can connect up to ten conductors of the same potential without tools — quickly, intuitively, and in a space-saving manner.

As always, this model offers the familiar benefits:

  • No loss of connection points compored to bridging solutions
  • Compact, double-deck design saves space
  • Suitable for fine-stranded conductors from 0.14 to 4 mm² and solid or stranded conductors from 0.2 to 4 mm²

nturally, the new version meets all the same technical standards and certifications as the existing 2-, 3-, and 5-conductor termal blocks of the 221 Series.

Available now in our shop.
