Wago 221 Series 2-Way Lever Connector for 0.14 - 4 mm² Wires

The Wago 221 Series 2-way lever connector is a professional-grade solution designed for the fast and reliable connection of solid, stranded, and fine-stranded conductors. With a capacity to handle wire cross-sections from 0.14 to 4 mm², this connector simplifies electrical installations by eliminating the need for traditional tools. Its compact design and intuitive lever mechanism ensure that electrical contacts are secure and consistent, making it an essential component for modern wiring projects in both residential and commercial settings.

Advantages

The primary benefit of the Wago 221 series is its user-friendly lever technology, which allows for quick wire insertion and removal without damaging the conductors. The transparent housing provides visual confirmation that the wire is correctly inserted and stripped to the proper length. Because the connector is reusable, it offers significant flexibility for temporary setups or future modifications. Furthermore, the compact dimensions allow for efficient use of space in crowded junction boxes, ensuring a clean and organized wiring environment.

Suitable for

• Connecting lighting fixtures in residential homes
• Wiring junction boxes in commercial buildings
• Extending or repairing existing electrical circuits
• Connecting fine-stranded wires in control cabinets

This connector is not intended for use with high-voltage industrial power lines or applications exceeding its rated electrical capacity. It is also not suitable for direct burial or underwater installations where moisture ingress could compromise the electrical connection.

Key specifications

• Connection type: Lever-operated spring pressure
• Wire range: 0.14 to 4 mm²
• Number of connection points: 2
• Width: 13.2 mm
• Depth: 18.6 mm
• Height: 8.4 mm

To use the connector, first strip the insulation from the wire to the recommended length. Lift the orange operating lever to the open position, insert the conductor fully into the terminal, and then push the lever back down to secure the connection. The spring-loaded mechanism automatically adjusts to the wire size, ensuring a firm grip and optimal electrical contact.

What to consider before purchase

• Ensure the total current load does not exceed the connector's rated capacity
• Verify that the wire cross-section falls within the specified 0.14 to 4 mm² range
• Confirm the number of connection points matches your specific wiring requirements

Always ensure that the power supply is completely disconnected before performing any electrical work. For best results, use only compatible wire types and ensure the insulation is stripped to the exact length indicated on the connector housing.
