Product information

Description

The Wago 281-687 is a professional-grade 3-conductor terminal block engineered for reliable electrical connections in demanding environments. Designed with a 4mm2 cross-section and featuring the standard green and yellow color coding, this component is specifically optimized for protective earth or grounding applications. Its robust construction ensures long-term stability and safety in industrial and commercial electrical systems, making it a trusted choice for engineers and electricians requiring precise and secure wiring solutions.

Advantages

This terminal block offers exceptional reliability through its advanced spring pressure connection technology, which maintains consistent contact force regardless of vibrations or thermal expansion. The compact design allows for high-density wiring, significantly saving space within control cabinets and distribution boards. Furthermore, the intuitive design facilitates rapid installation and maintenance, reducing labor time while ensuring that grounding connections meet stringent safety standards.

Suitable for

  • Grounding and protective earth connections in control panels
  • Industrial automation and machinery wiring
  • Commercial building electrical distribution systems
  • Modular terminal block assemblies in DIN-rail mounted configurations

When it may not be suitable

This terminal block is not intended for use with conductors exceeding the specified 4mm2 cross-section capacity. It is also not suitable for applications requiring high-current power distribution beyond its rated technical limits or for environments where exposure to extreme corrosive chemicals might compromise the integrity of the housing material.

Key specifications

  • Conductor capacity: 4mm2
  • Connection type: 3-conductor
  • Color: Green and Yellow
  • Width: 6 mm
  • Depth: 73.5 mm
  • Height: 29 mm

How to use

To use the Wago 281-687, mount the terminal block onto a standard DIN rail until it clicks securely into place. Strip the insulation from your conductors to the recommended length and insert them into the terminal openings. The spring-loaded mechanism automatically secures the wire, ensuring a vibration-proof connection without the need for manual screw tightening. To remove or adjust a wire, use a compatible operating tool to release the spring clamp.

What to consider before purchase

  • Verify that the 4mm2 wire size matches your specific project requirements
  • Ensure compatibility with your existing DIN rail mounting system
  • Confirm that the green and yellow color coding aligns with your local electrical safety regulations for grounding

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring operations. Use appropriate wire stripping tools to prevent damage to the conductor strands and ensure a clean, reliable connection within the terminal block.
