wago1019The "Compact" connecting terminal of the 221 series of Wago stands in the classic Electrical installation in Buildings for a quick, easy and safe wiring. Product managers, designers and developers at device manufacturers are now increasingly discovering the advantages of this terminal with a lever – from component manufacture to equipment production and device connection to the end product.

International approvals allow a wide range of possible applications. It also makes it easier for manufacturers to access the global sales market. The universal and flexible spring connection technology connects all types of conductors from 0,14 to 6 mm2 easily, quickly and safely without pre-treatment.

There is also a time and cost advantage compared to screwdriving technology and the Solder: just open the lever, in the ladder, close the lever. This tool-free and therefore convenient conductor connection simplifies the wiring and the complete device connection for the installer on site.

Country-specific approvals

The country-specific approvals (eg UL approvals, etc.), ship approvals and many more of the 221 series allow a wide range of applications. Likewise, the components and devices with the integrated 221 can be used worldwide.
