Wago Selection box 221 series terminals

Compact splice connectors for all types of wires. Now even smaller and easier to use. Delivered in a handy selection box. This selection box contains: 40 pieces of 2 x 4 mm², 30 pieces of 3 x 4 mm², and 15 pieces of 5 x 4 mm². Tried and perfected. This series is 40% smaller and even more user-friendly than its successful predecessor, the 222 series. The tool-free, lever-operated connectors of Wago's 221 series for electrical installations enable faster, more reliable connections of solid, stranded, and fine wires, while simultaneously reducing the space required in junction boxes. This is made possible not only by their compact design, which is 40% smaller than that of the established 222 series, but also by their transparent housing, easier handling, and two test ports.
