## Long description

The Wago 870-831 is a professional-grade 4-conductor through terminal block engineered for secure and efficient electrical distribution. Designed for mounting on standard DIN rails, this component facilitates organized wiring in industrial control cabinets and automation systems. Its compact design and robust construction ensure reliable performance in demanding electrical environments, making it a standard choice for engineers and technicians requiring high-density connectivity.
Advantages
This terminal block offers significant space-saving benefits due to its slim 5 mm width, allowing for a higher density of connections within limited enclosure spaces. The 4-conductor configuration simplifies complex wiring tasks by enabling multiple connections at a single potential point. Its high-quality materials provide long-term durability and vibration resistance, ensuring that electrical contacts remain stable over time, which reduces maintenance requirements in critical infrastructure.
Suitable for
Industrial control cabinets
Automation and process control systems
Electrical distribution panels
Complex wiring projects requiring multi-conductor junctions
When it may not be suitable
This terminal block is not intended for use with conductors exceeding 2.5 mm² in cross-section. It is also not suitable for high-current applications that exceed the specified electrical ratings or for environments requiring specialized ingress protection against moisture or dust beyond standard cabinet mounting.
Key specifications
Conductor capacity: 2.5 mm²
Number of connection points: 4
Rated voltage: 500 V
Width: 5 mm
Depth: 55 mm
Height: 27.5 mm
Mounting type: DIN-rail
How to use
To install the Wago 870-831, snap the terminal block onto a compatible DIN rail until it clicks securely into place. Strip the insulation from your conductors to the appropriate length and insert them into the spring-clamp terminals. Ensure the wires are fully seated to guarantee a secure electrical connection. Multiple blocks can be placed side-by-side to create a continuous terminal strip, and end plates or partitions should be used at the ends of the assembly for safety and structural integrity.
What to consider before purchase
Ensure the 2.5 mm² wire size is compatible with your specific application requirements.
Verify that the 500 V rating meets your system's voltage specifications.
Check the available space on your DIN rail to accommodate the 5 mm width per block.
Consider purchasing matching end plates and markers for a complete and organized installation.
Usage recommendations
Always ensure that the power supply is disconnected before performing any wiring work. Use appropriate wire stripping tools to avoid damaging the conductor strands, and verify that all connections are tight and properly seated before energizing the circuit.
