It ships with trip class 10A / 10E (preset) / 20E per IEC 60947-4-2, so it matches standard motor start profiles — 10A for normal starts, 10E for extended ramp, 20E for heavy inertia loads like crushers or centrifuges. The unit carries ATEX, UKEX, and IECEx certification, meaning it is approved for installation in explosive atmospheres (gas/dust zones) where a standard soft starter would be a safety violation. That certification alone sets it apart from the bulk of the SIRIUS catalog. ## Fieldbus and control integration This soft starter supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET standard — five protocols on one device. That means it drops into a Siemens PLC environment over PROFINET or PROFIBUS, but also into Rockwell or third-party networks via EtherNet/IP or Modbus TCP without a gateway. The control supply voltage is not listed here, but the remote reset function is confirmed: cycling the control supply off/on resets the unit. The analog output is configurable as 4-20 mA or 0-10 V, which feeds motor current or load status to a PLC analog input or local meter. Screw fixing is the fastening method — no DIN-rail clip on this frame. The dimensions are 160 mm wide, 230 mm high, 282 mm deep. Mounting position is flexible: vertical surface, ±90° rotatable, and ±22.5° tiltable forward/back. Shock resistance is rated at 15 g / 11 ms. That is enough for most industrial panels but worth checking if the enclosure is near a press or drop-forge.","metaTitle":"Siemens 3RW5073-6AB04 Soft Starter, ATEX/UKEX/IECEx","metaDescription":"Siemens 3RW5073-6AB04 soft starter with ATEX, UKEX, IECEx approvals. 100 A min, trip class 10A/10E/20E, multi-protocol (PROFIBUS, Modbus, EtherNet/IP","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Soft Starters"],"specifications":{"ATEX":"Yes","UKEX":"Yes","Depth":"282 mm","IECEx":"Yes","Width":"160 mm","title":"3RW5073-6AB04","Height":"230 mm","Minimum":"100 A","Upwards":"100 mm","Forwards":"10 mm","PROFIBUS":"Yes","Backwards":"0 mm","Downwards":"75 mm","CE marking":"Yes","Modbus RTU":"Yes","Modbus TCP":"Yes","Trip Class":"CLASS 10A / 10E (preset) / 20E;
