With the WAGO 221, manufacturers of lighting equipment and other electrical devices, the so-called OEMs, can rely on universal mounting carriers for a group of connectors because the WAGO 221 connect all conductor types from 0.14 to 6 mm² (28–10 AWG) easily, quickly and certainly reliably. It translates into tangible advantages in terms of time and money compared to traditional screw or welding technology. With WAGO Serie 221 it only takes to lift the lever, insert the conductor and lower the lever, all without tools. Ease of use is indeed the key to the success of this family of terminal blocks while maintaining the wiring safety unchanged.

In the world of electrical wiring, the wide range of worldwide applications of WAGO’s new 221 Series Inline Splicing Connector and accessories is made possible through the achievement of several national and international type- and use- certifications.

  • pioneering universal spring connection technology;
  • exhaustive international certifications obtained;
