That 90 A figure is the current the SSR can handle when mounted to an adequate heat sink — the datasheet calls out 'for mounting on available cooling surfaces', meaning this is not a free-air part. In a panel, you plan for a dedicated heatsink or a metal backplate that draws heat away; otherwise derating kicks in fast. The 22.5 mm DIN-rail width keeps the panel density high — one module wide, same as a miniature circuit breaker. Spring-loaded terminals (no screw torque to check) accept solid or ferruled stranded up to the rated cross-section, which wires up clean and saves a few seconds per termination on a build. ## Compliance and regulatory notes RoHS compliant since 15-01-24.","metaTitle":"Siemens 3RF3190-2AA22 SIRIUS 3RF31 SSR, 90 A, 22.5 mm","metaDescription":"Siemens 3RF3190-2AA22 SIRIUS 3RF31 solid-state relay, 1-pole, 90 A, 24-230 V / 110-230 V AC, spring terminals, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Solid State Relays"],"specifications":{"title":"3RF3190-2AA22","Group Code":"R711","description":"semiconductor relay, 1-pole 3RF3 width 22.5 mm, 90 A 24-230 V 110-230 V AC 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/ae69b9a4eaa0cd1053df016300a1cb5f.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RF3190-2AA22?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation does this part have?","answer":"RoHS compliant since 15-01-24.
