Terminal block Wago 221-613, 3-contact compact splicing connector for fine-stranded conductors 0.14–6 mm²

Wago 221-613 is a compact, three-contact splicing connector designed for quick and secure connections of fine-stranded conductors with cross-sections from 0.14 to 6 mm². The push-in connection system allows tool-free insertion and removal of conductors, providing reliable contact and the option for repeated reconnection. Its slim housing saves space in junction boxes, control cabinets and appliance housings while maintaining clear conductor separation for safe electrical distribution.

Advantages

The push-in mechanism enables fast, tool-free installation and simple reconnection when needed. The three-contact arrangement supports splicing and distribution in a single compact unit, reducing the number of individual connectors and saving space. The transparent or translucent housing area provides visual confirmation of conductor insertion and contact quality. The connector accepts a wide range of fine-stranded conductor sizes, making it versatile for different wiring tasks.

Suitable for

• Internal wiring of household and commercial junction boxes
• Appliance wiring and service connections
• Control panels and automation equipment
• Retrofit projects and repairs requiring tool-free reconnection

Key specifications

• Number of contacts: 3
• Conductor cross-section range: 0.14–6 mm² (fine-stranded)
• Connection type: push-in (tool-free insertion and removal)
• Contact material: corrosion-resistant metal alloy (spring clamp)
• Insulating body: compact, space-saving housing with visual area for conductor check
• Suitable conductor types: fine-stranded flexible conductors with ferrules or without, within specified range

How to use

Prepare conductors by stripping the insulation to the recommended length for the connector. Insert each conductor straight into the corresponding push-in port until it seats and visual confirmation of insertion is visible through the housing. For reconnection, withdraw the conductor by pulling it out while holding the connector body; if the connector design requires it, use the specified release method. Ensure conductors are inserted to the proper depth and that no bare conductor is exposed outside the insulating body. Observe applicable electrical safety standards and switch off power before making or changing connections.

Usage recommendations

Use Wago 221-613 connectors only within the specified conductor cross-section range (0.14–6 mm²) and with fine-stranded conductors as intended. Verify mechanical strain relief in installations where conductors may be pulled or moved, and avoid use in circuits exceeding the connector’s rated current and voltage per installation standards. For long-term reliability, periodically inspect connections in environments subject to vibration or temperature cycling.
