It handles an operating voltage range of 200...460 V AC and accepts a control supply voltage of 110...230 V AC/DC at 50/60 Hz. The integrated bypass contact system means the power electronics are bypassed once the motor reaches full speed, reducing heat dissipation in the panel. The 5.5 kW at 400 V is the 3-phase induction motor power this unit starts; the 7.5 hp at 50 °C is the equivalent for North American 460 V systems. Frame size S0 with screw and snap-on mounting fits standard DIN rails and occupies 45 mm width. The IP20 enclosure is open-style for panel mounting — not for washdown environments. Clearance: 60 mm above, 40 mm below, 15 mm at the sides for airflow. Dual-slope control lets you set separate start and stop voltage ramps — useful for pumps that need a soft stop to prevent water hammer, or conveyors that need a quick start but gentle stop. The integrated bypass switches the motor directly across the line after start, so the soft starter's thyristors cool off during run.","metaTitle":"Siemens 3RW3124-1CB14 SIRIUS Soft Starter, 12.5 A, Size S0","metaDescription":"Siemens 3RW3124-1CB14 SIRIUS soft starter, 12.5 A at 40 °C, 5.5 kW / 400 V, 200-460 V AC, UC 110-230 V, dual-slope control, screw terminals, IP20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Soft Starters"],"specifications":{"Depth":"125mm","Width":"45mm","Height":"125mm","Upwards":"60mm","Downwards":"40mm","At The Side":"15mm","Mounting type":"screw and snap-on mounting","lifecycle_stage":"current","During Operation":"-25 ... +60°C","Product brand name":"SIRIUS","Product designation":"soft starters for standard applications","Protection class IP":"IP20","Wire length maximum":"100m","Derating temperature":"40°C","at 40 °C rated value":"12.5A","at 50 °C rated value":"11A","at 60 °C rated value":"9A","For Main Current Circuit":"screw-type terminals","Motor Overload Protection":"No","Size of engine control device":"S0","Control supply voltage 1 at DC":"110 ... 230V","Operating frequency rated value":"50 ... 60Hz","Integrated Bypass Contact System":"Yes","Reference code acc. to DIN EN 61346-2":"Q","Control supply voltage 1 at AC at 50 Hz":"110 ... 230V","Control supply voltage 1 at AC at 60 Hz":"110 ... 230V","Number of poles for main current circuit":"3","Evaluation of thermistor motor protection":"No","For Auxiliary And Control Current Circuit":"screw-type terminals","at standard circuit at 40 °C rated value":"5 500W","at standard circuit at 50 °C rated value":"7.5hp","Number of CO contacts for auxiliary contacts":"0","Number of NC contacts for auxiliary contacts":"0","Number of NO contacts for auxiliary contacts":"0","Type of voltage of the control supply voltage":"AC/DC","Control supply voltage frequency 1 rated value":"50Hz","Control supply voltage frequency 2 rated value":"60Hz","Operating voltage at standard circuit rated value":"200 ... 460V"}},"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=53048&mlfb=3RW3124-1CB14","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RW3124-1CB14/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RW3124-1CB14","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RW3124-1CB14 when reusing this data.
