WAGO Connection Terminal Green Range flexible up to 4mm² - 221-422
WAGO Green Range Connecting Terminal with Lever – Series 221-422: Fast, Safe, and now more Sustainable
Even small changes can make a big difference – that's why the WAGO Series 221 connecting terminal has been revised. The new Green Range variant is partially made from bio-circular and recycled plastics, thereby 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 carrying capacity 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, eliminating the need for pre-treatment or ferrules. The compact dimensions (13.2 x 8.4 x 18.6 mm) allow for space-saving installation, while the transparent housing ensures quick visual inspection. The terminals in this series have two conductors, meaning two clamping points, and come in packs of 100.
Your advantages 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)
- Durable & safe – maintenance-free CAGE CLAMP® spring pressure connection 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 does wiring with WAGO terminals work?
WAGO terminals are very small and compact. Due to their extremely small dimensions, they are ideally suited for tight spaces. This makes the terminals very convenient to install and also creates free space for any future expansions. Operation is intuitive, and connecting conductors is quick and easy. The levers can be opened and closed with little effort. Thanks to lateral gripping recesses, the WAGO terminals are firmly held in every situation. The procedure for connecting conductors is as follows:
- Strip the desired conductors
- Open the WAGO terminal with the lever
- Insert the conductors
- Close the lever
The transparent housing allows you to continuously check the conductor position. The contact point is gas-tight, ensuring a permanently secure contact between the conductor and the busbar. Two easily accessible test ports (one is in the direction of the conductor entry and the other on the opposite side) make testing conditions very comfortable, even when installed. The application is suitable for ambient temperatures of up to 85 °C, and the maximum terminal temperature according to UL standard is 105°C. WAGO terminals have globally recognized approvals. If you want to disconnect conductors, this is also easily possible. As with insertion, the lever is opened and the cable is removed.
Areas of application for WAGO terminals
Connecting cables is one of the most common tasks when connecting electronic devices in the home, expanding a camper van, or installing solar modules. Since WAGO terminals can connect both stranded and solid conductors, their application possibilities are diverse. Additionally, the terminals can be used with any cable cross-section, which makes them flexible and compatible for every application. Two application examples are, for instance, connecting solar modules to charge controllers or connecting consumers to a battery.
With the Green Range, WAGO is committed to greater sustainability in electrical installation without compromising on quality and performance.
