The Siemens 3RW5226-3TC15 is a SIRIUS soft starter with a minimum operating current of 32 A. The Trip Class defaults to CLASS 10A per IEC 60947-4-2, with selectable 10E or 20E. Rated voltage spans 200 to 600 V. The control supply accepts 110–250 V at both 50 and 60 Hz. Fieldbus options are comprehensive: PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP are all onboard, plus PROFINET standard and PROFIenergy for energy management when paired with the PROFINET communication module. That's a single SKU that talks to most PLC ecosystems without an add-on gateway.
Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 5 mm at the sides, and 0 mm backward, so it can sit flush against the backplane. Overall footprint is 306 mm high by 185 mm wide by 203 mm deep — a substantial unit that needs a dedicated spot in the enclosure, not a DIN-rail clip-on. Shock resistance is 15 g / 11 ms, with potential contact lifting at 12 g / 11 ms, so it's fine for most industrial floors but not for direct mounting on a vibrating machine base without isolation.
