The Siemens 3RW5247-2TC05 is a SIRIUS soft starter rated for a minimum motor current of 200 A, with a Trip Class of CLASS 10A (default), 10E, or 20E per IEC 60947-4-2. The voltage range spans 200 to 600 V, covering 208 V, 400 V, and 480 V common in North American and European panels. Fieldbus support includes PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET — five protocols on one unit, so it drops into existing control architectures without a gateway. PROFIenergy is supported in conjunction with a PROFINET communication module, useful for energy-management profiles in automated lines. For a tire-curing press environment where ambient near the panel can hit 50 °C, plan the derate curve into the motor full-load current calculation. The 15 g / 11 ms shock resistance (with potential contact lifting at 12 g) means it holds up on vibrating machinery skids.
Screw fixing is the fastening method — no DIN-rail clip on this frame size. The mounting surface must be vertical, with ±90° rotatable and ±22.5° tiltable to front and back. Clearance requirements: 100 mm upwards, 10 mm forwards, 0 mm backwards, 75 mm downwards, 5 mm at the side. The 393 mm height and 210 mm width mean it fills a substantial portion of a 600 mm wide enclosure; verify gland-plate clearance for the 203 mm depth before laying out the backpanel.
