Rated for continuous operation per IEC 60947-6-2, it mounts on a standard DIN rail via screw and snap-on fastening, with a depth of 165 mm and height of 170 mm. ## Breaking capacity and trip class — what they mean for your line The adjustable Trip Class (CLASS 10 and 20) lets you match the overload curve to the motor start profile: Class 10 for short acceleration times (conveyors, pumps), Class 20 for high-inertia loads (fans, centrifuges) where the start current persists longer. ## Coil voltage and environmental endurance The control coil accepts 24 V AC/DC (50/60 Hz), simplifying wiring in panels with mixed supply — no separate DC power supply needed if the panel runs on 24 VDC. Vibration resistance to 20 m/s² at 5.8–500 Hz and shock resistance of 60 m/s² (6g) for 10 ms means it stays latched on a machine skid or near a press — no nuisance dropout.","metaTitle":"Siemens 3RA6250-0AB30 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA6250-0AB30 SIRIUS compact reversing starter, 53 kA breaking capacity at 400 V, adjustable Class 10/20, 24 V DC/AC coil.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Width":"90 mm","at DC":"24 ... 24 V","title":"3RA6250-0AB30","Height":"170 mm","at 400 V":"53 kA","at 50 Hz":"24 ... 24 V","at 60 Hz":"24 V","Trip Class":"CLASS 10 and 20 adjustable","Recommended":"vertical, on horizontal standard mounting rail","description":"SIRIUS Compact load feeder Reversing starter 690 V 24 V AC/DC 50...60 Hz 0.1...0.4 A IP20 Connection main circuit: plug-in, without terminals Connection control circuit: plug-in, without terminals","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","at AC maximum":"2.8 W","at DC maximum":"2.9 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":"24 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;
