## Long description

The Wago 279-837 is a high-quality 4-conductor terminal block engineered for secure and reliable electrical connections. With a rated cross-section of 1.5mm2, this component is specifically designed for grounding applications, featuring the standard green-yellow color coding for easy identification within electrical systems. Its robust construction ensures consistent performance in demanding industrial and commercial environments, providing a stable interface for complex wiring setups.
Advantages
This terminal block offers significant space savings due to its compact 4 mm width, allowing for high-density wiring in control cabinets. The 4-conductor design facilitates efficient potential distribution, reducing the need for additional bridging components. Its reliable clamping mechanism ensures vibration-resistant connections, which is essential for maintaining long-term electrical integrity in industrial machinery and control panels.
Suitable for
Grounding connections in industrial control cabinets
Commercial electrical distribution systems
High-density wiring applications where space is limited
Modular terminal block assemblies
When it may not be suitable
This terminal block is not intended for use with conductors exceeding the 1.5mm2 cross-section capacity. It is also not suitable for high-current power distribution applications that require larger wire gauges or specialized high-voltage insulation beyond its rated specifications.
Key specifications
Conductor capacity: 1.5mm2
Number of connection points: 4
Color: Green-Yellow
Width: 4 mm
Depth: 73 mm
Height: 27 mm
How to use
To use the Wago 279-837, strip the insulation from your conductor to the recommended length. Insert the wire into the clamping unit until it is fully seated. The spring-pressure connection technology automatically secures the wire, ensuring a gas-tight and vibration-proof contact without the need for manual screw tightening. To remove or adjust the wire, use a compatible operating tool to release the spring clamp.
What to consider before purchase
Ensure the conductor cross-section matches the 1.5mm2 rating
Verify that the green-yellow color coding aligns with your grounding requirements
Check the available rail space in your control cabinet against the 4 mm width
Confirm compatibility with your existing terminal block system
Usage recommendations
For optimal performance and safety, always ensure that the conductors are clean and stripped to the correct length before insertion. Avoid reusing damaged wires and ensure the terminal block is securely snapped onto the mounting rail before connecting any electrical loads.
