It switches a single change-over contact at 115 V AC/DC coil voltage, rated for a thermal current of 6 A. The hard gold-plated contacts suit low-level switching applications where oxidation resistance matters — think PLC outputs driving small signal loads or pilot devices. The narrow footprint means you can pack more isolation points per meter of rail compared to a standard-width interface relay. RoHS compliance is confirmed effective 26 September 2024, with a REACH Article 33 notification for lead content above 0.1% (CAS 7439-92-1) in the candidate list. No UL or CSA specific listing is in the evidence, but the export control classification is EAR99, meaning no special licensing for most destinations. The 115 V AC/DC coil voltage covers both common control voltages in a single variant — no need to pick AC or DC coil separately. The 6 A thermal current (Ith) is the continuous carry rating through the contacts; for motor or inductive loads, derate per the switching curve. Hard gold-plating on the contacts means this relay is specified for dry circuits or low-energy signals where standard silver alloy would tarnish and fail to conduct.","metaTitle":"Siemens 3RQ4118-1AE01 SIRIUS 3RQ4 Coupling Relay, 115 V AC/D","metaDescription":"Siemens 3RQ4118-1AE01 SIRIUS 3RQ4 output coupler with plug-in relay, 115 V AC/DC, 1 change-over contact, screw terminal, 6.2 mm wide, 6 A thermal current, hard gold-plated contacts","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Control Accessories"],"specifications":{"title":"3RQ4118-1AE01","Group Code":"R711","description":"output coupler with plug-in relay, 115 V AC/DC, 1 change-over contact, screw terminal, width 6.2 mm, thermal current 6 A, hard gold-plated","Product Group":"4950","Product class":"A: Standard product which is a stock item could be returned within the returns guidelines/period.","Quantity Unit":"1 Piece","Product Family":"SIRIUS 3RQ4 coupling relays, narrow design","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : EAR99","Packaging dimensions (L x W x H)":"95.00 x 93.00 x 65.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 26-09-24","REACH Art. 33 Duty to inform according to the current list of candidates":"Lead CAS-No. 7439-92-1 > 0,1 % (w / w)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b01706f3246c7dbf1acb589e2d6a93a4.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RQ4118-1AE01?tree=CatalogTree"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RQ4118-1AE01","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RQ4118-1AE01 when reusing this data.
