It's rated for continuous operation per IEC 60947-6-2, meaning it's built for sustained motor duty, not just occasional jogging. For a reversing starter this compact, that rating puts it squarely into high-fault-capability industrial panels. Motor power at 400 V is 5.5 kW, and the trip class is adjustable between CLASS 10 and CLASS 20. That adjustability lets you match the thermal curve to the motor's start profile — CLASS 10 for fast-starting loads like pumps, CLASS 20 for higher-inertia fans or conveyors. The control supply accepts 110–240 V AC/DC, which covers most global panel voltages without a separate transformer. Power consumption is low — 6 W AC, 5.1 W DC — so it won't stress a 24 VDC control supply if that's what you're running. Screw-and-snap-on fastening — clip it on, torque the main circuit terminals (screw-type, accepts 0.5–4 mm² solid or 2x 0.5–2.5 mm²), and wire the control voltage. Dimensions: 170 mm high, 90 mm wide, 165 mm deep. Vibration and shock resistance are specified: 6g shocks, 10 ms, three axes; vibration at 4–5.8 Hz with 15 mm amplitude, then 20 m/s² up to 500 Hz. That's enough for machine-mounted applications near motors or conveyors without derating.","metaTitle":"Siemens 3RA6250-1DP32 SIRIUS Compact Reversing Starter, 53 k","metaDescription":"Siemens 3RA6250-1DP32 SIRIUS compact reversing starter, 5.5 kW at 400 V, 53 kA breaking capacity, adjustable Class 10/20, screw terminals, DIN rail mount, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Solid":"0.5 ... 4 mm², 2x (0.5 ... 2.5 mm²)","Width":"90 mm","at DC":"110 ... 240 V","Height":"170 mm","at 400 V":"53 kA","at 50 Hz":"110 ... 240 V","at 60 Hz":"110 ... 240 V","Trip Class":"CLASS 10 and 20 adjustable","Recommended":"vertical, on horizontal standard DIN rail","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","at AC maximum":"6 W","at DC maximum":"5.1 W","During Storage":"-55 ... +80 °C","number of LEDs":"3","Type Of Voltage":"AC/DC","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"screw and snap-on mounting","IO-Link protocol":"No","Shock Resistance":"a=60 m/s2 (6g) with 10 ms per 3 shocks in all axes","Mounting Position":"any","at DC rated value":"240 V","Product Brand Name":"SIRIUS","Type Of Assignment":"continous operation according to IEC 60947-6-2","Degree Of Pollution":"3","Product Designation":"compact starter","Vibration Resistance":"f= 4 ... 5.8 Hz, d= 15 mm;
