## Long description

The Wago 280-520 is a professional-grade 4-pole double-level terminal block engineered for secure and efficient electrical wiring in demanding environments. This component is specifically designed to optimize space within control cabinets, offering a compact 5 mm width that allows for high-density wiring configurations. Finished in a professional grey, it provides reliable connectivity for conductors up to 2.5 mm², ensuring stable and long-lasting performance in both industrial and commercial electrical systems.
Advantages
The primary benefit of this double-level terminal block is its ability to maximize space efficiency without compromising on connection quality. By utilizing two levels of connectivity within a single 5 mm footprint, it significantly reduces the amount of rail space required for complex wiring setups. The robust design ensures a secure mechanical and electrical connection, which is essential for maintaining system integrity in vibration-prone environments. Its intuitive design facilitates quick installation and maintenance, making it a preferred choice for professional electrical engineers and panel builders.
Suitable for
High-density control cabinet installations
Industrial automation and control systems
Commercial electrical distribution panels
Modular wiring applications where space is limited
This terminal block may not be suitable for applications requiring the termination of conductors larger than 2.5 mm² or for environments where extreme environmental conditions exceed the standard specifications for thermoplastic insulation. It is also not intended for direct use in high-voltage power distribution networks beyond its rated capacity.
Key specifications
Number of poles: 4
Connection levels: 2
Width: 5 mm
Depth: 74 mm
Height: 58.5 mm
Conductor capacity: 2.5 mm²
Color: Grey
To use the Wago 280-520, mount the terminal block onto a standard DIN rail by snapping it into place. Strip the insulation from your conductors to the recommended length and insert them into the spring-clamp terminals. Ensure the wire is fully seated to establish a secure, vibration-resistant connection. The double-level design allows for organized routing of multiple circuits within a compact area, simplifying the overall wiring architecture of your control panel.
What to consider before purchase
Verify that the 2.5 mm² conductor capacity meets your specific wiring requirements.
Ensure the 5 mm width is compatible with your existing DIN rail layout.
Confirm the number of poles matches your circuit design needs.
For optimal performance and safety, always ensure that conductors are properly stripped and fully inserted into the terminal. Regularly inspect connections in high-vibration environments to maintain long-term system reliability.
