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.
