Wago 221-413 Compact Splicing Connector for 3 Conductors 0.5-4 mm² 20 Pieces

The Wago 221-413 compact splicing connector is a professional-grade solution for joining up to 3 electrical conductors quickly and safely. Designed for versatility, this connector accommodates solid, stranded, and fine-stranded wires with cross-sections ranging from 0.5 to 4 mm². Its intuitive lever-operated mechanism allows for tool-free installation, making it an essential component for modern electrical wiring tasks in both residential and commercial environments.

Advantages

The primary benefit of the Wago 221-413 is its ease of use, which significantly reduces installation time compared to traditional twisting or screw-based methods. The compact design allows for efficient space utilization in junction boxes, while the transparent housing provides visual confirmation that the wires are correctly inserted and stripped to the proper length. Furthermore, the integrated test ports allow for convenient voltage testing without needing to disconnect the wires, ensuring high safety standards and reliable electrical contact over time.

Suitable for

• Connecting lighting fixtures in residential ceilings
• Wiring electrical outlets and switches
• Branching circuits in junction boxes
• Temporary electrical setups requiring reliable connections
• Connecting fine-stranded wires in control cabinets

When it may not be suitable

This connector is not intended for use with wires exceeding the 4 mm² cross-section limit or for applications involving high-vibration environments where specialized locking mechanisms might be required. It is also not suitable for direct burial or underwater electrical installations without appropriate protective enclosures.

Key specifications

• Number of conductors: 3
• Wire cross-section: 0.5 to 4 mm²
• Maximum voltage: 450 V
• Maximum current: 32 A
• Color: Orange
• Quantity: 20 pieces

How to use

To use the connector, first strip approximately 11 mm of insulation from the end of each conductor. Lift the orange lever on the connector to the open position, insert the stripped wire fully into the terminal, and then push the lever back down to secure the connection. Repeat this process for each of the three ports as needed. The secure clamping force ensures a permanent and vibration-resistant connection.

What to consider before purchase

• Verify the total number of conductors needed for your specific circuit
• Ensure your wire gauge falls within the 0.5–4 mm² range
• Check that the operating voltage and current do not exceed the rated limits
• Confirm that the installation environment is dry and protected

Usage recommendations

Always ensure the power is disconnected before performing any electrical work. Use only compatible wire types and ensure they are stripped to the correct length to prevent exposed conductors or loose connections.
