The load supply range is 48–460 V AC, and the control input accepts 4–30 V DC — a low-voltage DC coil equivalent that interfaces directly with PLC or safety relay outputs without an interposing relay. ## Deployment context The 1-pole form factor suits single-phase resistive loads (heaters, lighting) or DC switching where a single pole is sufficient. Packaged individually, dimensions 105 x 27 x 122 mm — fits a standard 22.5 mm wide modular contactor footprint. The low control voltage (4–30 V DC) allows direct drive from 24 V DC PLC outputs without a separate power supply.","metaTitle":"Siemens 3RF3330-1DA44 SIRIUS solid-state contactor, 30 A AC-","metaDescription":"Siemens 3RF3330-1DA44 SIRIUS 3RF33 solid-state contactor, 1-pole, 30 A AC-1 at 40 °C, 48-460 V supply, 4-30 V DC control, screw terminal, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Solid State Relays"],"specifications":{"title":"3RF3330-1DA44","Group Code":"R711","description":"solid-state contactor 1-pole 3RF3 AC-1 / 30 A / 40 °C 48-460 V / 4-30 V DC short-circuit-proof up to 25 A with B miniature circuit breaker screw terminal","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 3RF33 solid-state contactors, 1-pole","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : 9N9999","Packaging dimensions (L x W x H)":"105.00 x 27.00 x 122.00 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/b88539c2282e6b91d1cf8b9d7df7e0da.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RF3330-1DA44?tree=CatalogTree"},"ai":{"faq":[{"question":"What is the group code and product group for this part?","answer":"The group code is R711 and the product group is 3725.
