The 22.5 mm wide housing uses spring-loaded terminals and is designed for mounting on a customer-supplied cooling surface — no internal heatsink, so the panel builder provides the thermal path. That 90 A rating at up to 600 VAC covers most three-phase motor loads, resistive heaters, and industrial lighting banks you'd find in a control cabinet. The 24 VDC coil is standard for PLC-driven outputs; it pulls the gate without the dropout chatter you get from marginal AC coils on a shared supply. But the big difference from a standard contactor: this relay has no internal heatsink, so the mounting surface (panel plate or a dedicated heatsink) must dissipate the I²R losses from 90 A.","metaTitle":"Siemens 3RF3190-2AA06 SIRIUS 3RF31 SSR, 90 A, 1-pole","metaDescription":"Siemens 3RF3190-2AA06 SIRIUS solid-state relay, 1-pole, 90 A, 48-600 VAC, 24 VDC control, spring terminals, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Solid State Relays"],"specifications":{"title":"3RF3190-2AA06","Group Code":"R711","description":"semiconductor relay, 1-pole 3RF3 width 22.5 mm, 90 A 48-600 V / 24 V DC spring-loaded terminal for mounting on available cooling surfaces","Product Group":"3725","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 3RF31 solid-state relays, 1-pole, 22.5 mm","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"104.00 x 44.00 x 48.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 15-01-24","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/c0732b3ce5988f038d44a50fb4c9e328.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RF3190-2AA06?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation is available for this part?","answer":"RoHS compliance is confirmed since 15 January 2024. The REACH Article 33 declaration identifies lead (CAS 7439-92-1) above 0.1% w/w in the semiconductor die. No UL or IEC certification numbers are listed in the product record, but the SIRIUS 3RF series typically carries cULus and IEC 60947-4-2 approvals — verify the specific certification mark on the unit or request the manufacturer's declaration."},{"question":"What does the 90 A rating mean for real-world motor loads?","answer":"The 90 A rating at 48-600 VAC covers most 30-40 hp three-phase induction motors at 480 V. But because this is a solid-state relay without an internal heatsink, the actual continuous current the relay can handle depends entirely on the thermal resistance of the mounting surface. For a 90 A resistive load (heater bank), a properly sized aluminum backplate or forced-air heatsink is mandatory. For motor starting, the inrush surge is brief enough that the thermal mass of a good mounting plate handles it — just don't bolt it to a thin sheet-metal panel and expect full rating."},{"question":"How do I source the 3RF3190-2AA06?","answer":"This is an active, standard-stock-class product (Product Class A), meaning it's a normal stock item through Siemens distribution channels. Submit an RFQ for current lead time and pricing; no special factory-order lead times or minimum quantities are indicated in the product record."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RF3190-2AA06","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/3RF3190-2AA06 when reusing this data.
