The WAGO 209-191 separator is a crucial component for installations requiring separation between Ex e and Ex i circuits. It ensures compliance with EN 50020 by maintaining a minimum distance of 50 mm between live parts, enabling a more compact layout when using common carrier rails. This separator is particularly useful in industrial environments where space is limited and safety regulations must be strictly adhered to. It is compatible with WAGO's 279 to 282 Series terminal blocks, offering a versatile solution for various electrical applications.
