Wago 221-413 3‑pole universal connector for solid/stranded conductors 0.2–4 mm² (pack 50)

Wago 221-413 is a 3-pole universal pushwire connector designed for connecting solid and stranded copper conductors with cross-sections from 0.2 to 4 mm². Supplied in a pack of 50, each connector features a transparent housing for visual inspection and a compact form factor suitable for wiring, lighting fixtures, junction boxes and quick repairs. The push-in mechanism allows tool-free, reversible connections that simplify installation and maintenance.

Advantages

The transparent, impact-resistant housing permits rapid visual verification of conductor insertion and contact integrity. The pushwire mechanism accepts both solid and stranded conductors without the need for ferrules or additional tools, reducing installation time. Reusability enables disconnection and reconnection during testing or modification. Small, robust body with clear conductor entry points supports space-efficient wiring arrangements.

Suitable for

• Domestic and commercial building wiring where 3-pole connections are required
• Lighting circuits and fixture connections
• Junction boxes, distribution blocks and terminal replacements
• Quick field repairs and temporary installations

When it may not be suitable

These connectors are intended for copper conductors within the specified cross-section range (0.2–4 mm²). They should not be used for conductors larger than the rated size, for aluminum conductors, or in applications that require specialized high-current or environmental sealing beyond the connector's basic protection. For installations subject to specific regulatory or product certification requirements, verify compatibility before use.

Key specifications

• Number of poles: 3
• Conductor cross-section range: 0.2–4 mm²
• Compatible conductor types: solid and stranded copper conductors
• Connection method: push-in (spring pressure) mechanism
• Housing material: transparent, impact-resistant plastic
• Reusability: disconnection and reconnection supported

How to use

Strip the conductor insulation to the recommended length, ensuring a clean, straight conductor end. Insert the stripped conductor into the appropriate entry until it seats firmly against the internal stop; the push-in mechanism will lock the conductor in place. To remove a conductor, use the specified release method for the connector family (press or pull according to manufacturer's guidance) and withdraw the wire. Perform a visual check through the transparent housing to confirm correct insertion and contact.

What to consider before purchase

• Confirm conductor type and cross-section fall within 0.2–4 mm²
• Ensure copper conductors are used; not intended for aluminium wires
• Check space available in boxes or panels for a 3-pole connector body
• Verify that the connector's performance meets any applicable local electrical regulations

Usage recommendations

Use these connectors for routine installations and maintenance where quick, tool-free connections are beneficial. Always follow local electrical codes and the manufacturer's instructions for stripping length and release procedure. For critical circuits or outdoor/exposed installations, choose connectors with appropriate environmental protection and certification.
