The trip class defaults to CLASS 10A per IEC 60947-4-2, with selectable 10E and 20E curves, so it handles standard and heavy-start loads like conveyors or crushers without nuisance tripping. Control voltage is 24 VDC, which keeps the panel wiring consistent with modern PLC-based control schemes. The unit supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET out of the box, plus PROFIenergy for coordinated energy management when paired with a PROFINET communication module. That makes it a drop-in for Siemens or Rockwell environments without needing a separate gateway. Screw-fixing mount on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back. Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 5 mm at the sides, and 0 mm backward. The 393 x 210 x 203 mm (H x W x D) envelope fits standard 800 mm wide enclosures with room for side-mounted bypass contactors. The CE marking covers the Low Voltage and EMC directives for industrial environments.","metaTitle":"Siemens 3RW5246-6TC04 SIRIUS Soft Starter, 160 A, 200-480 V","metaDescription":"Siemens 3RW5246-6TC04 SIRIUS soft starter, 160 A minimum, 200-480 VAC, Class 10A/10E/20E trip.
