Product details

Soft starter for motor starting in hazardous zones

The Siemens 3RW5524-3HA16 is a SIRIUS soft starter with ATEX and IECEx certification. It handles a rated voltage range of 200 to 690 V and offers selectable trip classes: CLASS 10A / 10E (default), 20E, or 30E per IEC 60947-4-2. Communication options include PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP, so it fits into most fieldbus architectures without a separate gateway. The unit also supports PROFIenergy in conjunction with PROFINET modules for energy management during idle periods.

The 3RW5524-3HA16 measures 185 mm wide, 306 mm high, and 203 mm deep. Clearance requirements: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, and zero behind. Screw terminals are not used — the unit uses spring-cage or ring-lug connections; verify the termination method matches your panel wiring practice.

Frequently asked questions

Does the 3RW5524-3HA16 support PROFIBUS communication?

Yes, the 3RW5524-3HA16 supports PROFIBUS, along with Modbus RTU, Modbus TCP, and EtherNet/IP.
