It is rated for AC-3 switching duty at 7.5 kW and 17 A on a 400 V three-phase line, which means it is sized for a standard 7.5 kW induction motor driving a conveyor, pump, or fan that needs direction reversal. The coil is 24 V DC, so it pulls in cleanly on a 24 VDC control supply without the dropout chatter you can get on an AC coil fed through a long cable run. The main power circuit terminates on screw-type terminals; the contactor frame is Size S0, which is the compact footprint in the SIRIUS line. The envelope is 100 mm wide by 100 mm deep by 86 mm tall, so it occupies a single 100 mm-wide module on the rail — plan your enclosure fill factor accordingly. No auxiliary contacts are built in — the listing shows zero NC and zero NO auxiliary contacts per direction of rotation. If your reversing starter needs aux contacts for status feedback or a holding circuit, you will need to add a separate auxiliary contact block alongside this assembly. ## Lifecycle and replacement This order code is a phased-out product per the manufacturer. The official Siemens successor is 3RA2325-8XB30-1BB4 — same Size S0, same 7.5 kW/400 V AC-3 rating, same 24 V DC coil and screw terminals, but built on the current SIRIUS 3RA2 platform. If you are filling a BOM line or replacing a failed unit in an existing panel, the successor drops into the same footprint and wiring scheme.","metaTitle":"Siemens 3RA1325-8XB30-1BB4 Reversing Contactor, 7.5 kW/400 V","metaDescription":"Siemens 3RA1325-8XB30-1BB4 reversing contactor assembly, AC-3 7.5 kW/400 V, 17 A, Size S0, 24 V DC coil, screw terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"100 mm","Width":"100 mm","Height":"86 mm","Mounting type":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","lifecycle_stage":"current","Product function":"Reversing contactor","Size of contactor":"S0","at DC rated value":"24 V","Protection class IP on the front":"IP20","Reference code acc. to DIN EN 61346-2":"Q","Reference code acc. to DIN EN 81346-2":"Q","Operating power at AC-3 at 400 V rated value":"7.5 kW","Type of voltage of the control supply voltage":"DC","Operating current at AC-3 at 400 V rated value":"17 A","Type of electrical connection for main current circuit":"screw-type terminals","Number of NC contacts for auxiliary contacts per direction of rotation":"0","Number of NO contacts for auxiliary contacts per direction of rotation":"0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=343765&mlfb=3RA1325-8XB30-1BB4","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA1325-8XB30-1BB4/alternatives.json"},"ai":{"faq":[{"question":"Is Siemens 3RA1325-8XB30-1BB4 obsolete?","answer":"Yes, this order code is a phased-out product.
