This SSR is designed for mounting on available cooling surfaces — meaning it needs a heatsink or a metal panel to dump its heat into. At 50 A, the junction losses add up; bolting it to a clean, flat metal surface with thermal compound is the difference between a relay that runs for years and one that cooks itself in six months. The 22.5 mm DIN-rail footprint matches standard terminal-block spacing, so it fits neatly alongside overload relays and contactors in a motor control bucket. Spring-loaded terminals: strip to 8 mm, push the wire in, done. No tool needed, which speeds up panel wiring on a build-out. RoHS compliant since January 15, 2024. Packaging dimensions are 104 x 44 x 48 mm, single unit per package.","metaTitle":"Siemens 3RF3150-2AA14 SIRIUS 3RF31 SSR, 50 A, 48-460 V","metaDescription":"Siemens 3RF3150-2AA14 SIRIUS 3RF31 solid-state relay, 1-pole, 22.5 mm, 50 A, 48-460 V, 24 V AC/DC control, spring-loaded terminals, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Solid State Relays"],"specifications":{"title":"3RF3150-2AA14","Group Code":"R711","description":"semiconductor relay, 1-pole 3RF3 width 22.5 mm, 50 A 48-460 V / 24 V AC/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/43062d336da2ce01f8bf0c2646c7a611.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RF3150-2AA14?tree=CatalogTree"},"ai":{"faq":[{"question":"What are the key ratings for the 3RF3150-2AA14?","answer":"50 A continuous load current, 48-460 V AC load voltage range, 24 V AC/DC control voltage.
