Product details

What this soft starter brings to the panel

The Siemens 3RW5547-2HA06 is a SIRIUS-series soft starter carrying ATEX and IECEx certification. Trip class is configurable from CLASS 10A / 10E (default) through 20E and 30E per IEC 60947-4-2. Rated voltage spans 200 to 690 V. Communication is fully wired for modern factory networks: Modbus RTU, Modbus TCP, PROFIBUS, and EtherNet/IP are all on board. That saves an external gateway and simplifies the control cabinet layout. The unit also supports PROFIenergy in connection with PROFINET Standard and PROFINET High-Feature communication modules, which allows energy-saving pauses during idle periods on automated lines. The 393 x 210 x 203 mm footprint (height x width x depth) plus clearance requirements (100 mm upward, 75 mm downward, 10 mm forward, 5 mm at the side, 0 mm backward) must be factored into the panel layout before cutting the gland plate.

Approvals include CE, UL, and CSA. ATEX and IECEx marks are the main differentiator from standard soft starters.

The adjustable trip class (10A/10E default, 20E, 30E) governs how long the soft starter allows the motor to draw starting current before the thermal model trips. Accuracy class is 5 per IEC 61557-12. Additional motor-control features include DC braking for rapid stopping, voltage ramp for gentle acceleration, pump ramp down to avoid water hammer, torque control, a breakaway pulse to crack stuck loads, and motor heating for anti-condensation in standby. The analog output is configurable as 4-20 mA (default) or 0-10 V, feeding motor current or other process values to a PLC or panel meter. Service factor is 1.15, matching the typical NEMA motor margin.

Frequently asked questions

Is 3RW5547-2HA06 suitable for ATEX environments?

Yes, the 3RW5547-2HA06 carries ATEX and IECEx certification, making it approved for starting motors in potentially explosive atmospheres. This is not a general-purpose unit — the hazardous-area declaration is a core spec.

Does 3RW5547-2HA06 support Modbus TCP communication?

Yes, Modbus TCP is supported natively, along with Modbus RTU, PROFIBUS, and EtherNet/IP. No external gateway is needed for these protocols.
