WAGO flexible connecting terminal up to 6mm² - 221-612

WAGO 221-612 connector for wiring

There are numerous types of connectors, whether the well-known screw terminal, junction box connector, or terminal block. With the WAGO connector, unlike all other connectors, you can connect any type of conductor completely tool-free.

Push-in connectors with a lever, such as the WAGO connector, are suitable for both multi-strand and solid electrical conductors.  Our range of WAGO connectors includes 2, 3, and 5-conductor connectors in the 4 and 6 mm² variants. This variety offers a wide range of applications, especially where different types of conductors and cross-sections meet. Connecting conductors is easier with these connectors than with any other, making wiring fast and reliable. When using screw terminals with multi-strand conductors, wire ferrules usually need to be attached. This step is not required with WAGO connectors, as there is no risk of wires protruding or being damaged by screws. Another major advantage is that conductors with different cross-sections can be attached to the connector. And all this without any special tools.

How do you wire WAGO connectors?

WAGO connectors are very small and compact. Due to their extremely small dimensions, they are ideal for tight spaces. This makes the connectors very easy to install and also leaves room for potential expansions. Operation is intuitive, and connecting the conductors is quick and easy. The levers can be opened and closed with minimal effort. Thanks to the recessed side grips, the WAGO connectors are securely held in place in every situation. The procedure for connecting conductors together is as follows:

1. Strip the desired conductors
2. Open the WAGO connector with the lever
3. Insert the conductors
4. Close the lever 

The transparent housing allows you to continuously check the position of the conductors. The contact point is gas-tight, ensuring a permanently secure connection between the conductor and the busbar. Two easily accessible inspection openings (one located towards the conductor connection and the other on the opposite side) make inspection very convenient even when installed. The connector is suitable for ambient temperatures of up to 85 °C, and the maximum connector temperature according to the UL standard is 105 °C. WAGO connectors have globally recognized approvals. If you want to disconnect the conductors again, this is also easily possible. As with insertion, the lever is opened and the cable is removed.

Applications of WAGO connectors

Connecting cables is one of the most common tasks when connecting electronic devices in the home, fitting out a camper, or installing solar panels. Since WAGO connectors can connect both multi-strand and solid conductors, their applications are versatile. In addition, the connectors can be used with any cable cross-section, making them highly flexible and compatible with any application. Two examples of applications are connecting solar panels to charge controllers or connecting consumers to a battery.
