Electrical connectors built for quick, secure two-conductor joins in small wiring tasks. Home electricians and installers will appreciate the tool-free lever action and compact, transparent design, WAGO Connection Terminal 221-412. Are these compact lever connectors versatile enough for everyday wiring needs?
⚡ At a Glance
- • Connection Reliability: Lever clamp secures 2 conductors, maintaining contact for repeated connections
- • Best for: Domestic electricians, installers and hobbyists working with small-gauge wiring
- • Not ideal for: Heavy duty industrial mains cables above 4 mm² or high-current installations
Two-conductor lever connectors accept 0.2–4 mm² conductors and come in a pack of 50. Transparent, compact design supports quick, reusable wire terminations in confined spaces.
Fast, tool-free connections – thanks to actuator lever
Actuator lever opens the clamp so conductors up to 4 mm² can be inserted, then closes to hold both solid and stranded wires securely. The two-conductor layout clamps each conductor independently.
Quick insert-and-close action reduces installation time and simplifies changes or maintenance without screwdrivers.
Clear visual checks – with transparent housing
Transparent body allows direct sight of conductor seating so installers can confirm correct insertion and clamping. Visible contact points help spot loose ends before powering circuits.
Visual confirmation lowers the risk of wiring errors and speeds inspection during and after installation.
Space-saving fit – with compact two-wire design
Small footprint and two-conductor configuration make the connectors suitable for congested junction boxes and compact fittings. The compact design is specifically noted for tight-space access.
Neat installations are easier to achieve in crowded enclosures, keeping wiring tidy and manageable.
