Wago 221-420 4mm 10-Way Connector 15 Pack

WAGO 221-420 — 10-Way Compact Lever Splicing Connector (Up to 4 mm², Transparent Housing)

The WAGO 221-420 is a professional-grade 10-way compact splicing connector designed for fast, reliable and completely tool-free wiring. Suitable for solid, stranded and fine-stranded copper conductors up to 4 mm², it uses WAGO’s proven CAGE CLAMP® technology to deliver secure, maintenance-free connections that resist vibration and thermal cycling.

With a transparent housing for instant visual inspection and orange levers for easy operation, the 221-420 ensures a quick, consistent finish across lighting, HVAC, control and distribution installations. Rated 32 A / 450 V (EN 60664), it’s ideal for high-load applications where safety, compactness and speed matter.

Fast, Safe, and Versatile Wiring: Connect up to ten conductors of the same potential in seconds — simply lift the lever, insert the wire to the 11 mm strip length, and close it. No screwdrivers or ferrules needed, saving time on-site and reducing rework.

Compact, Transparent & User-Friendly Design: The flat levers sit flush with the body for easy stacking inside junction boxes, while the transparent housing allows you to visually confirm full conductor insertion — essential for professional, inspection-ready jobs.

Universal Conductor Compatibility: Accepts solid, stranded and fine-stranded conductors (0.14–4 mm²) within one connector, reducing stock-holding and simplifying installation across mixed-cable projects.

Certified Safety & Durability: ENEC-, UL- and CCA-approved for global compliance, the 221-420 provides long-term reliability and thermal endurance up to 85 °C (T85). The lever’s rest position prevents accidental unclamping, ensuring robust safety in every installation.
