Its headline motor rating is 1500 W at 400 V (roughly 2 hp), with a 0.75 hp rating at 200/208 V, and it carries a 53 kA breaking capacity at 400 V — meaning it can safely interrupt a fault current up to that level without upstream devices needing to clear it, which simplifies panel coordination. The control circuit accepts AC or DC from 110 to 240 V at 50/60 Hz, drawing only 6 W AC or 5.1 W DC — a low burden on the control transformer. Trip class is adjustable between CLASS 10 and CLASS 20, so you can set it for standard motor start (Class 10) or longer acceleration times (Class 20) without swapping the overload block. ## Mounting, wiring, and panel fit The main circuit connects via plug-in terminals (no terminals included — order separately), accepting solid wire from 0.5 to 4 mm² or two conductors from 0.5 to 2.5 mm² per clamp. Three integrated LEDs give local status indication for run, fault, and power — useful for a quick visual check without a meter.","metaTitle":"Siemens 3RA6250-1CP33 SIRIUS Compact Reversing Starter","metaDescription":"Siemens 3RA6250-1CP33 SIRIUS compact reversing starter, 1500 W at 400 V, adjustable trip class 10/20, 53 kA breaking capacity, AC/DC 110-240 V control.","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","title":"3RA6250-1CP33","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","description":"SIRIUS Compact load feeder Reversing starter 690 V 110...240 V AC/DC 50...60 Hz 1...4 A IP20 Connection main circuit: plug-in, without terminals Connection control circuit: screw terminal","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;
