The WAGO 209-190 separator is a crucial component for installations requiring separation between Ex e II and Ex i circuits. It ensures compliance with EN 50020, which mandates a minimum distance of 50 mm between live parts of Ex e and Ex i circuits. This separator offers a space-saving solution when mounting Ex e and Ex i terminal blocks on a common carrier rail, making it ideal for applications where space is limited. It is compatible with WAGO's 279 to 282 Series terminal blocks and contributes to a safer and more organized electrical system. Proper installation requires ensuring the movable feet of the separator and terminal blocks face the same direction.
