Its minimum settable current is 20 A, which sets the floor for the motor FLA it can protect — anything below that and the overload curve won't calibrate correctly. Rated voltage spans 200 to 600 V, covering common low-voltage motor supplies from 208 V to 575 V without a separate tap. It also supports CLASS 10E and CLASS 20E for longer acceleration times on high-inertia loads like centrifuges or crushers. The 15% minimum load relative to the smallest settable Ie means you cannot set the overload below 15% of the soft starter's minimum rating, so match the motor FLA to at least 3 A for the 20 A floor. ## Panel fit and clearance dimensions The unit measures 306 mm high, 185 mm wide, and 203 mm deep, with screw fixing to the mounting surface. Clearance requirements: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, and 0 mm behind — the back can sit flush against the panel backplate. The mounting position allows ±10° rotation and can be tilted forward or backward on a vertical surface. Shock resistance is rated at 15 g for 11 ms, with potential contact lifting noted above 12 g — relevant if the panel is mounted on a vibrating machine base or near a large contactor bank. ## Fieldbus and control connectivity This soft starter supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET standard, plus PROFIenergy in connection with the PROFINET communication module. That covers most industrial Ethernet and serial fieldbus topologies without an external gateway. No analog output is fitted, and torque control is not available — this is a voltage-ramp soft starter, not a variable-speed drive. Remote reset is possible by cycling the control supply voltage off and on. Auto-reset is also configurable. The error logbook feature requires a special accessory — not included in the base unit. Firmware updates are supported, so the unit can be field-upgraded if the network protocol or protection logic needs revision. ## Approvals and compliance documentation The 3RW5224-3TC15 carries CE marking, UL approval, and CSA approval — accepted across European, US, and Canadian installations without additional agency review. Service factor is 1, meaning no continuous overload margin beyond the nameplate rating.","metaTitle":"Siemens 3RW5224-3TC15 SIRIUS Soft Starter, 20 A min","metaDescription":"Siemens 3RW5224-3TC15 SIRIUS soft starter, 20 A minimum current, 200-600 V rated voltage, Class 10A/10E/20E trip, PROFIBUS/Modbus/EtherNet/IP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Soft Starters"],"specifications":{"Depth":"203 mm","Width":"185 mm","title":"3RW5224-3TC15","Height":"306 mm","Minimum":"20 A","Upwards":"100 mm","Forwards":"10 mm","PROFIBUS":"Yes","at 50 Hz":"110 ... 250 V","at 60 Hz":"110 ... 250 V","Backwards":"0 mm","Downwards":"75 mm","CE marking":"Yes","Modbus RTU":"Yes","Modbus TCP":"Yes","Trip Class":"CLASS 10A (default) / 10E / 20E;
