Electrical through terminal block Wago KE-221-2411/WAGO – compact connector for wire joining

Wago KE-221-2411 is a compact through-type electrical terminal block designed to join conductors while maintaining circuit continuity. As a Wago compact connector, it features a space-saving body and a secure clamping mechanism that allows repeatable connections and disconnections without damaging conductors. The KE-221-2411 is intended for general wiring tasks in installations where a small, reliable, and reusable terminal is required.

Advantages

The compact form factor reduces space requirements in terminal strips and junction boxes while the through-type design enables current to pass straight through for easy inline connections. The connector provides consistent contact pressure for reliable electrical continuity and is suitable for repeated use during installation and maintenance. Its simple push-in or lever action (depending on the specific model family) ensures quick conductor insertion and reduces assembly time.

Suitable for

• Field wiring and junctions where inline continuity is needed
• Control cabinets and distribution boxes with limited space
• Temporary installations and maintenance tasks requiring reusable connections
• Joining solid, stranded, or ferruled conductors where a compact connector is preferred

Key specifications

• Through-type compact connector body suitable for inline conductor connections
• Designed for repeated insertion and removal of conductors without conductor damage
• Compatible with common conductor types: solid, stranded, and ferruled conductors (observe conductor size limits)
• Space-saving design for use in confined terminal strips and junction boxes
• Reliable contact pressure to maintain circuit continuity under normal operating conditions

How to use

Strip the conductor to the recommended length and insert it straight into the connector until secure contact is felt. For models with a lever or push-in mechanism, operate the actuator according to the connector family instructions before inserting or removing wires. Ensure conductors are fully seated and that insulation does not enter the contact area. Verify electrical continuity after installation and perform routine visual inspections during maintenance.

Usage recommendations

Use the connector within the conductor size and current-carrying limits specified by the manufacturer. Avoid using damaged or corroded conductors and ensure that the installation environment matches the connector's intended application (indoor dry locations or specified environmental conditions). For high-vibration or harsh environments, select an appropriate mounting method and periodically inspect the connections.
