WAGO 221-412 4mm² Compact Splicing Connector with Lever – Transparent Housing

Compact, capable splicing for tight spaces

Meet the WAGO 221-412, a 4mm² compact splicing connector designed for quick, dependable terminations in limited spaces. This 2-conductor connector uses orange operating levers to simplify insertion and release, while a transparent housing lets you visually verify each connection before power is applied.

Key design advantages

• Space-saving design: 40% smaller than its predecessor, making it easier to fit in crowded switch boxes and lighting fixtures.
• Easy wire insertion: orange levers reduce the force required for wiring, supporting faster, user-friendly terminations.
• Clear inspection: transparent housing lets you confirm a secure grip and proper seating at a glance.

Versatile wiring for copper leads

• Broad wire compatibility: supports solid, stranded, and fine-stranded copper wires from 24 to 12 AWG.
• Precise dimensions: compact footprint measures 1.177 inches wide, 0.327 inches high, and 0.732 inches long, ideal for constrained installations.
• Reliable construction: manufactured with attention to tolerance and consistency for repeatable connections.

Safety, standards, and real-world use

• Safety and compliance: UL listed, with a maximum operating temperature of 85°C and EN60664 conformity, plus UL 486C approvals for dependable electrical performance.
• Quality you can trust: German-made engineering combines durability with lower operating forces for comfortable, repeatable use.

In practical terms, the 221-412 shines in switch boxes, lighting fixtures, and other wiring tasks where space is at a premium. The combination of a transparent housing and lever-based operation supports easier verification, faster servicing, and tidier installations. While benefits vary with the application, this connector is positioned to help you achieve orderly, inspectable terminations without sacrificing reliability.

Note: Benefits described are possible outcomes based on design features and typical use cases; actual results depend on your specific setup and adherence to safety guidelines.
