Trip class 10A means it can handle a 10-second overload before tripping — standard for most pump and fan starts. If your motor has a longer acceleration time (high-inertia load like a centrifuge), switching to class 20E buys you 20 seconds before the thermal model trips. The default is 10A; you set it via the integrated HMI or fieldbus. That means if this lives in a non-ventilated panel next to a drive, expect to reduce the current setting or add forced air — the thermal model inside assumes free airflow at 40 °C. Fieldbus options are stacked: PROFIBUS, PROFINET (with PROFIenergy), Modbus RTU, Modbus TCP, and EtherNet/IP all on the same unit. No separate communication module needed for most networks — just wire the RJ45 or D-sub and set the node address. The PROFIenergy profile lets the PLC shut down the soft starter during idle periods to save panel power. Mounts via screw fixing (not DIN rail) on a vertical surface, with ±10° tilt allowed forward or backward. Clearance requirements: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, 0 mm behind. That 100 mm upward gap is for heat plume rise — skimp on it and the internal thyristor heatsink will recirculate hot air, accelerating the derating curve. Dimensions are 306 mm high, 185 mm wide, 203 mm deep — roughly a 12x7x8 inch box. It's not a slimline unit; plan for a full-height sub-panel bay. The screw terminals accept up to the cable size needed for 25.5 A minimum, but the actual power terminals are sized for the full rated current of the unit. Approvals include CE, UL, and CSA, covering most industrial markets in Europe and North America.","metaTitle":"Siemens 3RW5225-3TC05 SIRIUS Soft Starter, 200-600V","metaDescription":"Siemens 3RW5225-3TC05 SIRIUS soft starter, rated 200-600 V, trip class 10A/10E/20E per IEC 60947-4-2, with PROFIBUS, Modbus TCP/RTU, 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":"3RW5225-3TC05","Height":"306 mm","Minimum":"25.5 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 (default) / 10E / 20E;
