WAGO 870-837 4-Conductor Protective Earth Terminal Block, Green-Yellow, Non-Bridgeable

This WAGO 870-837 is a 4-conductor protective earth terminal block with CAGE CLAMP® connection technology, providing a reliable and maintenance-free connection for solid and fine-stranded conductors up to 4 mm². Its green-yellow housing clearly identifies it as a PE terminal according to standard color coding.

Advantages

The CAGE CLAMP® system ensures vibration-proof, gas-tight connections without the need for special tools or re-tightening. The terminal block is non-bridgeable, simplifying installation in applications where individual grounding points are required. It mounts on standard 35 mm DIN rails and supports a wide operating temperature range from -35 to +105 °C.
