Why Choose the WAGO 285-137 35 mm² Ground Terminal Block?

The WAGO 285-137 is a high-current 2-conductor ground terminal block designed for reliable protective earth connections in industrial electrical installations. With a nominal conductor size of 35 mm², this green-yellow terminal provides a secure connection between protective conductors and the DIN rail, making it suitable for control cabinets, machinery and power distribution equipment.

The terminal uses WAGO’s proven CAGE CLAMP® spring pressure connection technology, providing a vibration-resistant and maintenance-free alternative to conventional screw terminals. The spring connection maintains consistent contact pressure on the conductor without requiring periodic screw retightening, supporting dependable operation in demanding industrial environments.

Designed for DIN-35 rail mounting, the WAGO 285-137 combines high conductor capacity with straightforward panel integration. Its lateral marker slots allow clear identification within terminal assemblies, while the internationally recognised green-yellow colour provides immediate visual identification of the protective earth function.

Key Advantages

  • Heavy-duty 35 mm² protective earth terminal block for industrial installations.
  • 2-conductor connection for secure protective earth wiring.
  • Spring pressure connection provides reliable, vibration-resistant conductor termination.
  • Maintenance-free connection eliminates routine screw retightening.
  • Green-yellow housing clearly identifies the protective earth function.
  • Lateral marker slots support organised and clearly identified terminal assemblies.

Key Features

  • WAGO 285 Series high-current terminal block.
  • 35 mm² nominal conductor size.
  • 2-conductor ground / protective earth terminal.
  • CAGE CLAMP® spring pressure connection.
  • Direct protective connection to the mounting rail.
  • Designed for standard DIN-35 rail mounting.
  • Lateral marker slots for terminal identification.
  • Green-yellow colour coding for protective earth circuits.
  • Suitable for high-current industrial wiring and power distribution applications.

Reliable Protective Earth Connections for Industrial Systems

Protective earth terminal blocks provide a low-impedance connection between protective conductors and the equipment grounding system. The WAGO 285-137 is designed specifically for this function, connecting the protective conductor to the DIN rail while providing the secure mechanical and electrical performance required in industrial control and power installations.

The 285 Series is designed for larger conductor cross-sections and demanding power applications. By combining high-current conductor capacity with spring pressure connection technology, the 285-137 provides a practical solution for panel builders and machine manufacturers requiring dependable protective earth termination without the maintenance requirements associated with screw connections.

Typical Applications

  • Protective earth connections in industrial control panels.
  • Machine building and factory automation systems.
  • Power distribution cabinets and switchgear assemblies.
  • High-current electrical equipment and machinery.
  • Motor control and industrial drive panels.
  • Industrial power and protective conductor distribution.
