It switches a 3-phase motor up to 4 kW at 400 V in AC-3 duty (9 A rated operational current), so it handles standard induction motor reversing — conveyors, pumps, fans — where you need direction change without a separate mechanical interlock. The 230 V AC coil (50/60 Hz) pulls in reliably across the -25 to +60 °C operating range, and the screw-type main terminals accept the wire sizes typical for this current class. ## Lifecycle status and the replacement path This part is explicitly marked as a phased-out product. The official Siemens successor is the SIRIUS 3RA2 series, with the preferred replacement order code 3RA2316-8XB34-1CP0. If you're filling a BOM line or a panel spare, that 3RA2 variant is the drop-in functional equivalent — same Size S00, same 230 V AC coil, same AC-3 4 kW / 9 A rating, same auxiliary contact configuration. ## What you get on the auxiliary side and the varistor The varistor is already plugged onto the coil terminals, so you don't need to source a separate suppression module for the AC coil. The assembly measures 90 mm wide, 72 mm deep, and 67 mm tall — Size S00 footprint. The 90 mm width means it occupies about 5 TE (terminal units) on the rail.","metaTitle":"Siemens 3RA1316-8XB34-1CP0 Reversing Contactor, AC-3 4kW","metaDescription":"Siemens 3RA1316-8XB34-1CP0 reversing contactor assembly, AC-3 4kW/400V, 9A, Size S00, 230V AC coil, 50/60Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"72 mm","Width":"90 mm","Height":"67 mm","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","lifecycle_stage":"current","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 50022","Product Function":"Reversing contactor","Size Of Contactor":"S00","at 50 Hz rated value":"230 V","at 60 Hz rated value":"230 V","Substance Prohibitance (Date)":"07/01/2006","protection class IP on the front":"IP20","Ambient Temperature During Operation":"-25 ... +60 °C","reference code according to IEC 81346-2":"Q","operating power at AC-3 at 400 V rated value":"4 kW","Type Of Voltage Of The Control Supply Voltage":"AC","operational current at AC-3 at 400 V rated value":"9 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","number of NC contacts for auxiliary contacts per direction of rotation":"2","number of NO contacts for auxiliary contacts per direction of rotation":"2"}},"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=465282&mlfb=3RA1316-8XB34-1CP0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA1316-8XB34-1CP0/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for 3RA1316-8XB34-1CP0?","answer":"The preferred successor is Siemens 3RA2316-8XB34-1CP0.
