The 221 Series Lever-Nuts®

The 221 Series Lever-Nuts® splicing connector sets new standards with its compact, user-friendly design for 24-10 AWG conductors. It offers quick, reliable connections for solid, stranded, and flexible wires, with a transparent housing for easy inspection and a low-effort lever operation.

Introducing the WAGO Green Range Splicing Connector with Levers: a sustainable evolution of our 221 Series. Crafted from partially bio-circular and recycled plastics, this connector supports environmental impact by extending resource life and promoting eco-friendly practices right from the start.

Quickly and easily connect all conductor types of different cross sections using two-, three-, and five-wire Connectors. The 221 Series Connectors accommodate Solid, Stranded and Fine-stranded conductors in two variants from 12-24AWG and 10-20AWG.

You can open WAGO’s splicing connectors easily and quickly. Opening the levers on the 221 Series requires little effort. This means you can connect conductors quickly – and without any tools! While connecting the conductor, recessed handles on the sides ensure an easy, secure grip on the connector.

With the new 221 Series Splicing Connectors, you can now test the voltage from both sides – even when installed. The connectors have two test slots right where the WAGO imprint appears: one in the conductor entry direction and one on the opposite side. This accessibility provides extremely convenient testing conditions, even after installation, within a wide range of applications. Every connector variant also provides a secure contact for all standard test probes.

Mounting carriers are available for every 221 Series Splicing Connector – whether it's the two-, three- or five-wire model. They can be mounted vertically or horizontally. Secure the carrier by snapping it onto the DIN-rail, or with screws on smooth surfaces. The flexible mounting clamps simplify both connector insertion and removal. Conductors can be conveniently connected and removed before or after inserting a connector into the carrier. One test slot is always accessible, ensuring compliance with VDE standards.

The mounting carriers are ideal for distribution extensions with WAGO’s 221 Series Splicing Connectors. The versions in dark gray/yellow and blue clearly distinguish the distributions of neutral and PE conductors in the control cabinet. The clear installation allows fast troubleshooting and maintenance.

WAGO's jumper increases the number of clamping points for the WAGO 221 Series Splicing Connectors on one potential. It creates potential distributions with up to eight connection points in the DIN-rail adapter and is available in four variants: with or without a locking contact point lever, both available in blue or gray.

Things can get confusing wherever multiple cables meet. WAGO’s junction box helps you connect up to 60 conductors with WAGO’s 221 Series Splicing Connector for all conductor types with cross-sections up to 12 AWG (4 mm²).
