It carries Group Code R711 and Product Group 4950, which are internal Siemens identifiers for logistics and catalog routing — useful when cross-referencing against a BOM or a legacy spare-parts list. RoHS compliant since 26-09-24, and REACH Article 33 information is available on request — both matter for OEMs shipping into EU-regulated markets or for quality-doc control tracking substance declarations. Export control is classified as AL: N / ECCN: N, meaning no special licensing is required for standard cross-border shipments — relevant for traders or multi-site procurement consolidating from a single source. ## Physical fit and packaging Packaged individually (quantity unit 1 piece), with dimensions 95 x 93 x 65 mm — narrow enough for dense DIN-rail layouts typical in SIRIUS control assemblies.","metaTitle":"3RQ4900-0A SIRIUS 3RQ4 coupling relay, narrow design, potent","metaDescription":"3RQ4900-0A from SIRIUS 3RQ4 series.
