## Summary description

The Wago 280-687 is a 3-conductor terminal block designed for secure electrical connections. Featuring a 2.5mm2 cross-section and a distinct green-yellow color for grounding applications, this component ensures reliable wire termination in industrial and control cabinet installations. Its compact design allows for efficient space utilization in DIN rail mounting systems.

## Long description

The Wago 280-687 is a professional-grade 3-conductor terminal block engineered for secure and reliable electrical grounding connections. Designed with a 2.5mm2 cross-section, this component is specifically color-coded in green and yellow to meet industry standards for protective earth (PE) applications. Its robust construction ensures stable wire termination, making it an essential element for maintaining safety and organization within complex electrical control cabinets and industrial automation systems.
Advantages
This terminal block offers significant benefits for electrical installations by providing a high-density connection solution that saves valuable space on DIN rails. The 3-conductor design allows for efficient branching of grounding wires, reducing the need for additional connectors and simplifying the overall wiring architecture. Its durable materials and precise engineering ensure long-term mechanical stability and low contact resistance, which are critical for maintaining the integrity of grounding circuits in demanding environments.
Suitable for
Grounding applications in industrial control panels
Automation and instrumentation systems
Distribution boards requiring reliable PE connections
DIN rail mounted electrical installations
When it may not be suitable
This terminal block is not intended for use with wire sizes exceeding 2.5mm2, as the clamping mechanism is specifically calibrated for this range. It is also not suitable for high-voltage power distribution applications that require specialized insulation or larger conductor cross-sections beyond its technical rating.
Key specifications
Conductor capacity: 2.5mm2
Connection type: 3-conductor
Color: Green-Yellow
Width: 5 mm
Depth: 64 mm
Height: 28 mm
Mounting: DIN rail
How to use
To use the Wago 280-687, first ensure the DIN rail is properly installed and grounded. Strip the insulation from your wires to the recommended length. Insert the wire into the terminal opening until it is firmly seated. The spring-pressure connection technology automatically secures the wire, providing a vibration-resistant contact. To remove or adjust a wire, use a suitable operating tool to release the clamping mechanism.
What to consider before purchase
Verify that your wire cross-section is compatible with the 2.5mm2 rating
Ensure the green-yellow color coding aligns with your local electrical safety regulations for grounding
Check the available space on your DIN rail to accommodate the 5mm width of the block
Usage recommendations: Always ensure that the DIN rail itself is properly connected to the main protective earth system to guarantee the effectiveness of the grounding terminal block.
