Electrical connector block Wago 221 series, model WAGO-221-415 (pack 25)

Compact Wago 221-series electrical connector block WAGO-221-415 in a pack of 25 is a removable lever connector designed for tool-free connection of solid, stranded and fine-stranded conductors. The connector provides reliable electrical contact and mechanical retention for branch, extension and repair wiring in household and light commercial installations. Its transparent housing allows visual inspection of conductor insertion while the lever mechanism enables quick connection, disconnection and reuse, offering a space-saving alternative to traditional screw terminals.

Advantages

The lever-actuated design permits effortless, tool-free wiring and repeated reuse without degrading connection quality. A transparent polycarbonate housing gives visual confirmation of correct conductor placement and contact. Compact dimensions reduce occupied space inside junction boxes and enclosures, simplifying installation in tight or crowded wiring environments. The connector accepts a range of conductor types and cross-sections, combining versatility with consistent mechanical and electrical performance.

Suitable for

• Household lighting and power circuits for branch or repair connections
• Extension and modification of wiring in kitchens, bathrooms and living areas
• Light commercial installations where quick and repeatable wiring changes are needed
• Temporary connections during testing or equipment replacement

Key specifications

• Connection type: lever-actuated push-in connector for tool-free operation
• Conductors accepted: solid, stranded and fine-stranded conductors (with ferrules)
• Pack quantity: 25 pieces
• Housing: transparent insulating material for visual inspection
• Mounting: free-standing or inside junction boxes and enclosures

How to use

Open the lever to the vertical position, insert the prepared conductor fully into the corresponding entry until it seats against the stop, then close the lever until it latches. For fine-stranded conductors, use ferrules where recommended or clamp according to manufacturer guidance to ensure secure contact. To disconnect, open the lever and withdraw the conductor. Repeat the process for each conductor; the connectors are designed for repeated opening and closing without tools.

Usage recommendations

Verify conductor sizes and insulation stripping lengths before installation. Do not exceed the rated conductor cross-section or use the connector for mains voltages or currents beyond the product’s specifications. Ensure connections are made within suitable enclosures and that local electrical codes and safety practices are followed. For repeated fine-stranded conductor connections, consider using ferrules to maintain long-term mechanical reliability.
