The 50 A rating is the continuous resistive load capacity at the rated voltage range — so it handles a 50 A heater bank or similar resistive load without derating, but for motor or transformer loads you need to check the inrush and apply the manufacturer's duty-cycle derating. This is a semiconductor relay designed for mounting on an available cooling surface (heatsink or panel metal), not a free-standing block — the thermal path to the panel is what lets it carry that current. No torque driver needed, which speeds up wiring on a multi-relay bank. Because it's a semiconductor relay with no moving contacts, there's zero contact bounce and no arc on break, so it's quiet and doesn't generate the electrical noise a mechanical contactor does. That matters when the relay shares a panel with sensitive control electronics.","metaTitle":"Siemens 3RF3150-2AA04 SIRIUS Solid-State Relay, 50 A, 22.5 m","metaDescription":"Siemens 3RF3150-2AA04 SIRIUS 3RF31 solid-state relay, 1-pole, 50 A, 48-460 VAC / 24 VDC 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":"3RF3150-2AA04","Group Code":"R711","description":"semiconductor relay, 1-pole 3RF3 width 22.5 mm, 50 A 48-460 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/15f16d2b60e7cd30ed9a00d4ff93abf5.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RF3150-2AA04?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation does Siemens provide for this part?","answer":"The part is RoHS compliant since 15-01-24 and has a REACH Article 33 disclosure for lead (CAS 7439-92-1) above 0.1% w/w in the candidate list.
