WAGO Green Range flexible connecting terminal up to 4mm² - 221-423

WAGO Green Range connection terminal with lever – Series 221-423: Fast, safe and now more sustainable

Even small changes can make a big difference – that is why the WAGO connection terminal of the 221 series has been redesigned. The new Green Range variant is partially made of bio-circular and recycled plastics, thus contributing to the conservation of natural resources. Without compromising on quality and safety, it remains the proven solution for fast, safe and flexible electrical installation.

With a rated voltage of 450 V and a current rating of up to 32 A, the terminal is ideal for a wide range of applications. Thanks to the innovative CAGE CLAMP® technology, conductors can be connected without tools, without the need for preparation or wire ferrules. The compact dimensions (18.8 x 8.4 x 18.6 mm) enable space-saving installation, while the transparent housing ensures quick visual inspection. The terminals in this series have three conductors, thus three connection points, and come in a pack of 50.

Your benefits at a glance:

• Fast & easy installation – tool-free connection with lever mechanism
• Universally applicable – for solid, stranded and fine-stranded conductors (0.2 mm² to 4 mm²)
• Long-lasting & safe – maintenance-free cage clamp technology for permanent connections
• Sustainable materials – contains recycled plastics (e.g. from PET bottles) and bio-based residues
• Conservation of fossil resources – through the recycling of existing materials
• Certified quality – identical performance to the classic 221 series

How does wiring with WAGO terminals work?

WAGO terminals are very small and compact. Due to their extremely small dimensions, they are ideal for tight spaces. This makes the terminals very easy to install and also creates space for potential expansions. Operation is intuitive and connecting the conductors is done quickly and easily. The levers can be opened and closed with little effort. Thanks to the side grip recesses, the WAGO terminals are firmly in hand in every situation. The procedure for connecting conductors together is as follows:

1. Strip the desired conductors
2. Open the WAGO terminal 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, which ensures a permanently safe contact of the conductor with the busbar. Two easily accessible test openings (one is located in the conductor connection direction and the other on the opposite side) make the testing conditions very convenient even in the installed state. The application is suitable for ambient temperatures of up to 85 °C and the maximum terminal temperature according to the UL standard is 105°C. WAGO terminals have globally recognized approvals. If you want to disconnect conductors from each other again, this is also easily possible. As with inserting, the lever is opened here and the cable is removed.

Application areas of WAGO terminals

Connecting cables is one of the most common tasks when connecting electronic devices in the household, when equipping a camper or when installing solar modules. Since WAGO terminals can connect both stranded and solid conductors, the possible uses are versatile. In addition, the terminals can be used with any cable cross-section, which makes them so flexible and compatible with any application. Two application examples are, for example, connecting solar modules to charge controllers or connecting consumers to a battery.

With the Green Range, WAGO is focusing on more sustainability in electrical installation without compromising on quality and performance.
