221 series connectors:

Proven and perfected: 221 Series connectors for all wire types set new standards. This new series is 40 % smaller and even more user-friendly than its successful predecessor, the 222 Series.

221 Series’ new “superstars” for electrical installations allow solid, stranded and fine-stranded wires to be connected faster, in less space and more reliably: This is not just made possible by their compact design, which is 40 % smaller than the well-established 222 Series, but also by their transparent housing, easier handling and two test ports.

Due to their extremely small dimensions, 221 Series’ COMPACT Splicing Connectors are ideal for space-restricted applications. Installation is made much easier, while providing additional freedom for future expansions.

221 Series’ new splicing connectors are also easier to use: The operating levers can now be opened and closed using noticeably less force. Lateral hollowed-out grips provide a firm hold on the 221 Series in any situation.
