## Long description

The Wago 280-519 4-pole double-level terminal block is a professional-grade component engineered for secure and efficient electrical wire management. Designed with a compact 5 mm width, this grey terminal block allows for high-density wiring in control cabinets and industrial automation systems. Its double-level architecture effectively doubles the connection capacity within the same footprint, making it an essential tool for complex electrical installations requiring reliable conductivity and organized cable routing for 2.5 mm² conductors.
Advantages
This terminal block offers significant space-saving benefits due to its double-level design, which is particularly advantageous in confined control panels where every millimeter counts. The robust construction ensures long-term mechanical stability and consistent electrical contact, reducing the risk of connection failures. Its compatibility with standard DIN-rail mounting systems facilitates quick and easy installation, while the clear, grey housing helps maintain a professional and organized appearance in any industrial setup.
Suitable for
Industrial control cabinets
Automation and process control systems
Electrical distribution panels
High-density wiring applications
Projects requiring 2.5 mm² conductor connections
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 applications requiring high-current power distribution beyond the rated capacity of standard terminal blocks or for environments where specialized explosion-proof or high-IP-rated enclosures are mandatory.
Key specifications
Number of poles: 4
Connection levels: 2
Conductor cross-section: 2.5 mm²
Width: 5 mm
Mounting type: DIN-rail
Color: Grey
How to use
To use the Wago 280-519, snap the terminal block onto a standard DIN-rail until it clicks securely into place. Strip the insulation from your wires to the recommended length and insert them into the connection points. Ensure the wires are fully seated to guarantee a reliable electrical connection. If multiple blocks are used, they can be grouped together to create a structured terminal strip for complex circuit management.
What to consider before purchase
Verify that your conductor size is compatible with the 2.5 mm² rating.
Ensure you have sufficient DIN-rail space for the number of blocks required.
Check if additional accessories like end plates or markers are needed for your specific installation.
Usage recommendations: Always ensure that the power is disconnected before performing any wiring tasks. Use appropriate wire stripping tools to avoid damaging the conductors and ensure a clean, secure fit within the terminal block.
