## Long description

The Wago 279-831 is a high-quality 4-conductor through terminal block engineered for reliable electrical connectivity within DIN rail mounting systems. This component is specifically designed to facilitate secure wire termination for conductors ranging from 0.08 to 1.5 mm², making it a versatile solution for various electrical infrastructure projects. Its compact design allows for high-density wiring, ensuring that space within control cabinets and distribution boards is utilized efficiently without compromising on connection integrity.
Advantages
The primary benefit of this terminal block is its robust 4-conductor design, which simplifies complex wiring tasks by allowing multiple connections at a single terminal point. The use of advanced spring pressure connection technology ensures that wires remain securely fastened even under conditions of vibration or thermal expansion, reducing the need for ongoing maintenance. Furthermore, the compact physical dimensions of the unit enable engineers to maximize the available space in crowded electrical panels, facilitating a cleaner and more organized installation.
Suitable for
Industrial control panels
Electrical distribution boards
Automation and control systems
Building installation wiring
This terminal block may not be suitable for applications requiring the connection of conductors larger than 1.5 mm² or for environments where extreme chemical exposure or high-pressure water ingress is present without appropriate protective enclosures.
Key specifications
Conductor cross-section: 0.08 to 1.5 mm²
Number of connection points: 4
Mounting type: DIN rail
Width: 4 mm
Depth: 73 mm
Height: 27 mm
How to use
To use the Wago 279-831, first ensure the DIN rail is securely installed in your enclosure. Snap the terminal block onto the rail until it clicks into place. Strip the insulation from your conductors to the recommended length. Using a suitable operating tool, open the clamping unit, insert the conductor fully into the terminal, and release the tool to secure the connection. Repeat this process for all four connection points as required by your circuit design.
What to consider before purchase
Ensure the conductor size is within the 0.08–1.5 mm² range.
Verify that the DIN rail type is compatible with the mounting mechanism.
Check the total current and voltage requirements of your circuit against the terminal block ratings.
Usage recommendations
Always ensure that power is disconnected from the circuit before performing any wiring operations to prevent electrical shock or damage to the components.
