Rated motor power 15 kW at 400 V, with HP equivalents 7.5 hp at 200/208 V, 10 hp at 220/230 V, and 20 hp at 460/480 V. ## Coil voltage and control wiring AC/DC coil 110-240 V, 50/60 Hz — common industrial control voltage, works on both AC and DC supplies without a separate rectifier module. ## Mechanical endurance for machine-mounted use Shock rated 60 m/s² (6g) for 10 ms, three shocks per axis; vibration tested 4-5.8 Hz at 15 mm amplitude, 5.8-500 Hz at 20 m/s², 10 cycles — survives the vibration environment on a machine base or conveyor frame.","metaTitle":"Siemens 3RA6120-0EP30 SIRIUS Compact Motor Starter","metaDescription":"Siemens 3RA6120-0EP30 SIRIUS compact motor starter, 15 kW at 400 V, 53 kA breaking capacity, CLASS 10/20 adjustable trip, AC/DC 110-240 V coil.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Width":"45 mm","at DC":"110 ... 240 V","title":"3RA6120-0EP30","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 mounting rail","description":"SIRIUS Compact load feeder DOL starter 690 V 110...240 V AC/DC 50...60 Hz 8...32 A IP20 Connection main circuit: plug-in, without terminals Connection auxiliary circuit: plug-in, without terminals","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","at AC maximum":"5.2 W","at DC maximum":"5.8 W","During Storage":"-55 ... +80 °C","number of LEDs":"2","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;
