The Siemens 3RW5213-1AC14 is a SIRIUS soft starter rated for motor control from 200 to 480 V AC (50/60 Hz). Its Trip Class defaults to CLASS 10A per IEC 60947-4-2, meaning it protects standard induction motors during start-up by limiting thermal stress — you can also select CLASS 10E or 20E via parameterization for heavier starting duties like high-inertia loads. The unit mounts via screw fixing to a vertical surface, with +/-10° tilt allowance, and requires 100 mm clearance upward and 75 mm downward for airflow — plan your enclosure layout accordingly. Minimum settable motor current is 5.5 A, and minimum load is 15% of that setting.
Fieldbus and control integration
This soft starter ships with onboard PROFIBUS and can be ordered with optional Modbus RTU, Modbus TCP, EtherNet/IP, or PROFINET communication modules — all listed as supported. The control supply voltage accepts 110-250 V AC at line frequency. A 4-20 mA analog output is standard, parameterizable to 0-10 V via the High Feature HMI accessory. Remote reset is possible by cycling the control supply voltage.
