WAGO 221-2421 Inline Splicing Connector with Levers 2-Conductor 4 mm²

The WAGO 221-2421 is a 221 Series inline splicing connector with levers, designed for connecting solid, stranded, and fine-stranded copper conductors in a single tool-free operation. Using CAGE CLAMP technology, it is rated for 450 V / 32 A per EN 60664 and accepts conductor cross-sections from 0.2 to 4 mm². The transparent housing provides immediate visual inspection of conductor contact without disassembly.

Features and benefits:

• Tool-free conductor connection and disconnection via wide lever design - conductors can be inserted or removed without any tool
• Connects solid, stranded, and fine-stranded conductors in one connector, eliminating the need to match conductor types at a joint
• Slim 8.1 × 8.9 mm cross-section saves space in confined installation areas such as back boxes and junction housings
• Fixed positioning and multi-pole installation possible using a compatible mounting carrier
• Housing partially made from post-consumer recyclate and bio-based residual materials, reducing reliance on fossil resources

Applications:

• Splicing supply conductors to electrical ovens and built-in appliances
• Joining conductors of differing types when wiring intercom systems
• In-line conductor extensions inside junction boxes and enclosures
• Installations requiring moisture protection when combined with WAGO Gelbox 207-1372
