221-2421 – WAGO | Inline splicing connector with levers; for all conductor types; max. 4 mm²; 2-conductor; transparent housing; white cover; Surrounding air temperature: max 85°C (T85); 4,00 mm²; transparent

Description

The WAGO 221-2421 is a revolutionary inline splicing connector that brings the ease of the 221 Series to a slim, space-saving design. Perfect for connecting conductors in tight spaces, this 2-conductor connector features a transparent housing and white cover, allowing for instant visual verification of proper strip length and complete conductor insertion. Equipped with intuitive green levers, it supports tool-free termination of all conductor types—solid, stranded, and fine-stranded—up to 4 mm² (12 AWG). Whether you are extending cables in a junction box or repairing damaged wires, the 221-2421 provides a secure, maintenance-free connection that is significantly more compact than traditional splicing methods.

Key Features

• Tool-Free Lever Technology: Simple lever actuation ensures fast and easy wiring for all users, providing a secure clamp that is resistant to vibration.
• Slim Inline Design: Optimized for small spaces, the narrow profile is ideal for through-hole connections and tight wiring enclosures.
• Transparent Housing: Clear polycarbonate shell allows for a quick “window” check to ensure the conductor is fully inserted and stripped correctly.
• Universal Compatibility: Connects solid, stranded, and fine-stranded copper wires from 0.2 to 4 mm² (20–12 AWG).
• High Temperature Rating: Rated for a surrounding air temperature of 85°C (T85) and continuous operating temperatures up to 105°C.
• Eco-Friendly Materials: Constructed using bio-circular PC and PBT materials, supporting sustainable installation practices.
