Wago 221-412 2-conductor wire connector Cage Clamp 450V Orange Transparent

The Wago 221-412 2-conductor wire connector featuring Cage Clamp technology is engineered for secure and reliable electrical connections. Designed with a rated voltage of 450 V, this compact splicing connector accommodates solid, stranded, and flexible conductors ranging from 0.2 to 4 mm². The transparent and orange housing incorporates operating levers, allowing for visual inspection of the connection and easy manipulation during installation. Weighing 1.6 g with a width of 13.1 mm and a depth of 18.6 mm, this component is compliant with RoHS standards and built to withstand a maximum ambient operating temperature of 85 °C.

Advantages

This 2-conductor wire connector utilizes advanced Cage Clamp technology to ensure dependable and maintenance-free electrical contacts without the need for tools. The transparent housing design provides immediate visual confirmation that the conductor is fully inserted and correctly stripped, minimizing installation errors. Operating levers simplify the opening and closing of clamping units, making connection and disconnection fast and effortless. The compact dimensions allow for space-saving organization inside junction boxes, while the high maximum operating temperature supports demanding application environments.

Suitable for

• Connecting solid, stranded, and flexible electrical conductors in residential and commercial buildings
• Electrical wiring projects requiring fast and tool-free installation using operating levers
• Junction boxes with limited space where compact 2-conductor wire connectors are necessary
• Visual inspection of electrical contact quality through a transparent housing

When it may not be suitable

This connector is not designed for underwater or direct-burial applications without appropriate weatherproof enclosures. It should not be used with conductor cross-sections outside the specified range of 0.2 to 4 mm² or subjected to voltages exceeding the 450 V rating.

How to use

To use the Wago 221-412 wire connector, first strip the electrical conductor to the appropriate length. Lift the operating lever of the connector upward until it is fully open. Insert the stripped conductor into the clamping unit until it reaches the stop. Push the operating lever back down into the closed position to secure the conductor firmly in place. Verify the correct insertion depth and secure connection through the transparent housing walls.

What to consider before purchase

• Verify that the conductor cross-section falls within the 0.2 to 4 mm² range
• Ensure the electrical circuit voltage does not exceed 450 V
• Check that the maximum ambient operating temperature remains at or below 85 °C
• Assess space requirements inside junction boxes to ensure proper fit of the compact connectors

Usage recommendations

Always disconnect the electrical power supply before installing or servicing any wiring components. Ensure that conductors are stripped to the manufacturer-recommended length and fully inserted into the terminal before closing the operating lever.
