The 221 Series from WAGO – Flexible, Fast and Safe

COMPACT Splicing Connector; for all conductor types; max. 4 mm²; 2-conductor; with levers; transparent housing; Surrounding air temperature: max 85°C (T85); 4,00 mm²; transparent

Quick and Easy to use. Opening the levers on the 221 Series requires little effort. This means you can connect conductors quickly – without tools. Simply pull up the lever, insert the stripped conductor and push the lever back down.
The transparent housing allows you to clearly see if the wires are stripped to the correct length and connected properly.
The connector has two test slots located below where the WAGO imprint appears: one in the conductor entry direction and one on the opposite side. This allows easy testing, even when installed.

This tool-free, lever-actuated connector is suitable for a wide variety of industrial applications.
