Wago 221 Series Inline Splicing Connectors

A truly standard-setting solution for all conductor types from 0.2 to 4 mm²

The new 221 Series Inline Splicing Connector with lever combines all the trusted advantages of the 221 Series Splicing Connectors into a slim design.

Offering unsurpassed simplicity, speed and reliability, the 221 Series provides universal conductor connections – with lever technology that eliminates tools – while offering a visibly secure conductor contact. Where multiple poles are required, optional adapters provide completely modular mounting. Users get the flexibility of having five fixed-position poles in one adapter – whether it’s with or without strain relief, on DIN-rails with a snap-in mounting foot, for screw mounting, adhesive mounting, tie-on mounting or suspended mounting. As a universal connection technology, the 221 Series Inline Splicing Connector’s compact dimensions not only improve your current installations, the small footprint also opens up a wide variety of new applications. These include space-restricted applications like laboratory and test setups, production test bays, lighting connection in suspended ceilings, or extending loudspeaker cables and distribution boxes in industrial applications.

Your Benefits:

Connecting solid, stranded and fine-stranded conductors from 0.2 to 4 mm² in the feedthrough direction
Slim design minimizes dimensions for installation in tight spaces
Tool-free connection and disconnection thanks to convenient lever technology
Choosing between fixed-position installation and multi-pole installation with an adapter

Overview of Applications

Inline Connection of Installation Lines

As a universal connection technology, the 221 Series Inline Splicing Connector’s compact dimensions not only improve current installations, the small footprint also allows for a wide variety of new applications, such as the inline connection of installation lines in junction boxes (e.g., for light connection in suspended ceilings).

Perfect for Test Setups

Pull the lever up, insert a conductor and push the lever back down! The slim 221 Series Inline Splicing Connector is a universal tool that’s ideal for lab and test setups or production test stands – and does not require the use of any tools while providing visible confirmation of conductor contact. Disconnecting conductors is just as quick and easy: raise the lever, remove the conductor, lower the lever.

Multiple Poles and Fixed-Position Installation via Adapter

Whether in devices or on DIN-rails – the adapters for the 221 Series Inline Splicing Connector provide completely modular mounting. Users get the flexibility of having five fixed-position poles in one adapter – whether it’s with or without strain relief, on DIN-rails with a snap-in mounting foot, for screw mounting, adhesive mounting, tie-on mounting or suspended mounting.
