The control coil is 110-230 V AC. It comes in a 22.5 mm wide housing with spring-loaded terminals, designed to be mounted on a cooling surface to dissipate heat. The 50 A rating is the continuous load current the SSR can handle with proper heatsinking. Because it's a semiconductor relay, it switches without mechanical contacts, so it's suited for high-cycle applications like temperature control or motor starting where contact wear is a concern. The 48-600 V range covers common industrial voltages from 48 V control circuits up to 480/600 V motor feeds. The 22.5 mm width matches standard DIN-rail component spacing, but note this relay requires a cooling surface — it doesn't dissipate full rated current free-air. Panel builders should budget for a metal backplate or dedicated heatsink. RoHS compliant since 15 January 2024. No export restrictions under German AL or US ECCN (AL: N / ECCN: N). The product family documentation includes the standard Siemens declaration of conformity; no separate UL or IEC listing is on this record, but the SIRIUS 3RF series typically carries cULus and CE marks — verify the specific nameplate for your jurisdiction. Mounts on a cooling surface — the 22.5 mm width means it fits alongside other SIRIUS components on the same DIN rail, but the relay body must be thermally coupled to a metal panel or heatsink to reach 50 A. The packaging dimensions (104 x 44 x 48 mm) give the outer carton size, not the relay itself.","metaTitle":"Siemens 3RF3150-2AA26 SIRIUS 3RF31 SSR, 50 A, 1-pole, 22.5 m","metaDescription":"Siemens 3RF3150-2AA26 SIRIUS 3RF31 solid-state relay, 1-pole, 50 A, 48-600 V, 110-230 V AC coil, spring terminals, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Solid State Relays"],"specifications":{"title":"3RF3150-2AA26","Group Code":"R711","description":"semiconductor relay, 1-pole 3RF3 width 22.5 mm, 50 A 48-600 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/faffae44bc56fbf96dcea50c240e0990.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RF3150-2AA26?tree=CatalogTree"},"ai":{"faq":[{"question":"What is the closest alternative to 3RF3150-2AA26 in the same family?","answer":"Within the SIRIUS 3RF31 series, the closest pin-compatible alternative would be a different current rating or coil voltage variant in the same 22.5 mm 1-pole form factor. The 3RF31 family shares the same footprint and terminal layout, so swapping a 50 A unit for a 30 A or 75 A version (if available) is a direct mechanical fit, provided the cooling surface is adequate for the new rating."},{"question":"What is the group code (R711) and product group (3725) for this part?","answer":"The group code is R711 and the product group is 3725.
