221 Series at a Glance

The Unbeatable Benefits of the 221

Lift Lever, Insert Conductor, Close Lever

221 Series Splicing Connector for all conductor types ranging in size from 0.14 to 6 mm2 (26–10 AWG)

  • Connect solid, stranded and fine-stranded conductors
  • Time savings for installers and device manufacturers
  • Quickly install devices with higher levels of power consumption
  • Safely install long cable runs with larger conductor cross sections
Conductor Range

Two Sizes for All Conductor Types

Quickly and easily connect all conductor types of different cross sections using two-, three-, and five-wire connectors. The new connectors accommodate fine-stranded conductors from 0.14 to 4 mm2 (28–12 AWG), as well as solid and stranded conductors from 0.2 to 4 mm2 (24–12 AWG). With the 6 mm2 (10 AWG) variant, connect all conductor types – with cross sections from 0.5 to 6 mm2 (2−10 AWG).

Easier Actuation

Extremely Easy to Use

You can open WAGO's Splicing Connectors easily and quickly. Opening the levers on the Series 221 takes very little effort. This means you can connect conductors quickly – and without a single tool! While you are connecting the conductor, recessed handles on the sides ensure an easy, secure grip on the connector.

Test Slots

Two Test Slots

With the new 221 Series Splicing Connectors, you can now test the voltage from two different sides – even when installed. The connectors carry two test slots right where the WAGO imprint is shown: 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. All connector variants also provide a secure contact for all standard test probes.

Mounting Carriers

WAGO's 221 Series Conquers Distribution Cabinets

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 as well as 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. A test slot is always accessible, ensuring compliance with VDE standards.
