Wago Through connector

Through connector of the 221 series. Slim design and tool-free conductor connection. A groundbreaking conductor connection for all conductor types from 0.2 to 4 mm² - unmatched in simplicity, speed, and safety. The new through connector of the 221 series with lever combines all the known advantages of the 221 connection terminal series in a sleek design: a universal conductor connection that is completely tool-free thanks to lever technology and provides visibly secure conductor contact.

Where multipolarity is required, adapters offer users individual degrees of freedom for the modular, flexible assembly of up to 5 fixed-position poles in one adapter - whether with or without strain relief, on mounting rails with snap feet, for screwing, gluing, binding, or hanging.

As a universal connection medium, the through connector of the 221 series not only enhances well-known installation applications with limited space requirements but also opens up a variety of new applications: for example, laboratory and test setups, production testing fields, lighting connections in false ceilings, extension of speaker cables, and junction boxes in industrial applications.

The through connector is available in two variants, both of which have EN and UL approvals: in the version with a transparent cover for conductor cross-sections from 0.2 to 4 mm² for all common applications, as well as in the version predominantly used in North America with a white cover for the extended connection range with AWG-12 conductor. Fixed-position and multipolar: With the adapters for the through connector of the 221 series, users gain individual degrees of freedom for the modular, flexible assembly of up to 5 fixed-position poles in one adapter - whether with or without strain relief, on mounting rails with snap feet, for screwing, gluing, binding, or hanging.
