The stainless steel enclosure carries a flameproof (Ex d) rating, so it mounts directly in Zone 1 gas groups without a purge system. This is the variant for both Ex and non-Ex environments, meaning one part number covers the installation class if the line straddles classified and unclassified zones. ## Cross-reference identifiers Group code R3P2 and product group 4759 are the internal Siemens classification tags. These matter if you are reconciling a BOM against a legacy SAP catalog or matching a spare to a plant master data record — the group code is the faster cross-check than the full order code when pulling from a central stores list.","metaTitle":"Siemens 6DR5526-.....-....
