{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3RW5217-1AC14","brand":"Siemens","brandSlug":"siemens","productSlug":"3RW5217-1AC14","canonicalUrl":"https://aoctrl.com/siemens/3RW5217-1AC14","factsUrl":"https://aoctrl.com/api/mcp/products/3RW5217-1AC14","rawCanonicalId":null},"summary":{"shortDescription":"Siemens 3RW5217-1AC14 soft starter, 200-480 V, 15.5 A minimum, Trip Class 10A, PROFIBUS, Modbus RTU/TCP, EtherNet/IP, PROFINET, screw fixing, 275 x 170 x 152 mm.","salesMarkdown":"## Trip Class 10A and the 15.5 A minimum — what they mean for motor starting The 3RW5217-1AC14: This soft starter is set by default to Trip Class 10A per IEC 60947-4-2, meaning it will disconnect the motor if the start current persists beyond the 10-second thermal limit of the class. That's the standard for most pump and fan starts where the load accelerates quickly. You can also select Class 10E or 20E if the application needs a longer start ramp. The minimum settable operating current is 15.5 A, and the minimum load is 15 % relative to that value. That means the unit can handle motors drawing as little as ~2.3 A during the start phase, which covers small conveyors and light-duty pumps without needing a downsized starter. ## Fieldbus options — PROFIBUS, Modbus, EtherNet/IP, PROFINET The 3RW5217-1AC14 ships with onboard PROFIBUS and Modbus RTU, plus support for Modbus TCP, EtherNet/IP, and PROFINET. That covers the major industrial Ethernet and serial fieldbus standards without an add-on module. If you need PROFIenergy, it works with the PROFINET standard communication module. The analog output defaults to 4-20 mA but can be parameterized to 0-10 V if you use the High Feature HMI. That gives you a speed or current signal back to the PLC without a separate transducer. ## Mounting and clearance — panel fit for a 275 x 170 x 152 mm unit The unit measures 275 mm high, 170 mm wide, and 152 mm deep. That gives flexibility in tight enclosures. Clearance requirements: 100 mm upwards, 75 mm downwards, 10 mm forwards, 0 mm backwards, and 5 mm at the sides. The backwards zero clearance means it can sit flush against the back panel, which saves depth in shallow cabinets. The power terminals accept solid wire: two terminals for 1.0-2.5 mm² and two for 2.5-10 mm². That covers standard motor cable sizes up to about 8 AWG. ## Operating temperature and derating — plan for the 40 °C threshold The unit operates from -25 °C to +60 °C, but Siemens flags derating at 40 °C or above. If the panel ambient runs hot, expect to reduce the continuous current rating. The shock resistance is 15 g for 11 ms, dropping to 12 g if contact lifting is a concern. Approvals include UL, CSA, and CE marking, covering North American and European installations. The product category is hybrid switching devices, which means it combines semiconductor and electromechanical switching for reduced heat dissipation during run.","metaTitle":"Siemens 3RW5217-1AC14 Soft Starter, 200-480 V, 15.5 A","metaDescription":"Siemens 3RW5217-1AC14 soft starter, rated 200-480 V, 15.5 A minimum.
