WAGO connecting terminal Green Range flexible up to 4mm² - 221-422

WAGO Green Range lever connector – Series 221-422: fast, safe and now more sustainable

Even small changes can make a big difference – that is why the WAGO Series 221 connector has been redesigned. The new Green Range version is partially made from bio-circular and recycled plastics, thus helping to conserve 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 connector 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 (13.2 x 8.4 x 18.6 mm) enable space-saving installation, while the transparent housing ensures quick visual inspection. The connectors in this series have two conductors, therefore two connection points, and come in packs of 100.

Your benefits at a glance:

• Fast & easy installation – tool-free connection with lever mechanism
• Universal application – for solid, stranded and fine-stranded conductors (0.2 mm² to 4 mm²)
• Long-lasting & safe – maintenance-free cage spring 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 Series 221

How do you connect conductors with 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 creates space 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 side grip recesses, the WAGO connectors remain firmly in hand 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 safe connection between the conductor and the busbar. Two easily accessible inspection openings (one is located in the conductor connection direction and the other on the opposite side) make inspection very convenient even when installed. The product 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 conductors from each other again, this is also easily possible. Just like when inserting, 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 stranded and solid conductors, their range of applications is versatile. In addition, the connectors can be used with any cable cross-section, making them so flexible and compatible with any application. Two application examples are, for example, connecting solar panels to charge controllers or connecting consumers to a battery.

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