Forget traditional terminal blocks and time-consuming screwing. The WAGO 221 connectors feature an extremely practical opening and closing lever, which allows for easy insertion and release of cables in seconds. All you need to do is lift the orange lever, insert the stripped conductor, and lower the lever for a perfectly secure connection.

Designed to meet the most stringent safety standards, these feed-through connectors are ideal for both residential electrical installations and demanding industrial applications. Their transparent housing allows you to visually check whether the cable has been properly inserted, while the integrated test port makes it easy to measure voltage without having to disconnect the wires.
