Rated 370 W at 400 V (AC-3 duty per IEC 60947-6-2), it draws 1.25 A per phase in continuous operation — sized for small conveyors, pumps, and actuator drives up to 0.5 hp at 460/480 V. The IO-Link interface (COM2, 38.4 kBaud) streams diagnostic data — coil status, trip class, overload count — back to the controller, so a line-side PLC sees the starter's health without hardwired feedback. ## Short-circuit coordination and trip tuning Rated breaking capacity of 53 kA at 400 V — this starter coordinates with upstream MCCBs or fuses to clear a bolted fault without damaging the contactor, critical for panel SCCR compliance. Trip class is adjustable between CLASS 10 and CLASS 20, letting you match the overload curve to the motor's starting profile — CLASS 10 for fast-starting pumps, CLASS 20 for high-inertia loads like fans or centrifuges. The reversing starter's main contacts are rated for 10 million mechanical operations; no-load switching frequency reaches 3,600 cycles per hour, so it handles frequent reversing in indexing or positioning applications. Mounts on standard 35 mm DIN rail (EN 60715) with screw and snap-on fastening — the 90 mm width and 165 mm depth fit a standard 200 mm deep enclosure with room for gland plates. Operates from -20 to +60 °C ambient; storage and transport range is -55 to +80 °C. Shock rated at 60 m/s² (6g) and vibration tested to 20 m/s² at 5.8–500 Hz — suitable for machine-mounted panels near rotating equipment. Sourced through authorized industrial distribution channels.","metaTitle":"Siemens 3RA6500-1BB42 SIRIUS Compact Starter, 370W, 53kA","metaDescription":"Siemens 3RA6500-1BB42 SIRIUS compact reversing starter for IO-Link. 370W at 400V, 53kA breaking capacity, adjustable trip class 10/20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Solid":"0.5 ... 4 mm², 2x (0.5 ... 2.5 mm²)","Width":"90 mm","at DC":"24 ... 24 V","title":"3RA6500-1BB42","Height":"170 mm","at 400 V":"53 kA","Trip Class":"CLASS 10 and 20 adjustable","Recommended":"vertical, on horizontal standard DIN rail","description":"SIRIUS Compact load feeder Reversing starter for IO-Link 690 V 24 V DC 0.32...1.25 A IP20 Connection main circuit: Screw terminal Connection control circuit: screw terminal","at DC maximum":"2.9 W","During Storage":"-55 ... +80 °C","number of LEDs":"5","Type Of Voltage":"DC","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"screw and snap-on mounting","IO-Link protocol":"Yes","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 for IO-Link","Vibration Resistance":"f= 4 ... 5.8 Hz, d= 15 mm;
