Rated for continuous operation per IEC 60947-6-2, it handles reversing duty for motors up to 0.09 kW at AC-3 400 V, with a breaking capacity of 53 kA at 400 V — enough to clear high-fault-current branches without cascading upstream. The trip class is adjustable between CLASS 10 and CLASS 20, so the same starter can be set for a faster trip on a pump (CLASS 10) or a slower trip on a high-inertia fan (CLASS 20) without swapping the overload block. ## IO-Link integration and control voltage Built-in IO-Link protocol at COM2 (38.4 kBaud) gives the PLC direct access to the starter's status, current draw, and trip history — no separate digital inputs needed for feedback. The coil is 24 V DC only (24... 24 V), so the control transformer must supply DC; an AC coil variant is not available on this order code. Five on-board LEDs indicate operating state, fault, and IO-Link communication — useful for commissioning without a handheld tool. ## Mounting and environmental limits for panel integration Mounts via screw and snap-on to a standard mounting rail; the manufacturer recommends vertical orientation on a horizontal rail for optimal heat dissipation. Dimensions are 90 mm wide, 191 mm tall, 165 mm deep — fits a standard 200 mm deep enclosure with room for wiring ducts. Operating temperature range is -20 to +60 °C, with storage and transport limits of -55 to +80 °C; pollution degree 3 means it tolerates conductive dust in industrial environments. Main circuit connection uses plug-in terminals without screw clamps — solid wire from 0.25 to 1.5 mm² is accepted, so pre-fabricated ferruled leads are recommended for stranded wire.","metaTitle":"Siemens 3RA6500-2AB43 SIRIUS Compact Reversing Starter","metaDescription":"Siemens 3RA6500-2AB43 SIRIUS compact reversing starter, 53 kA breaking capacity at 400 V, IO-Link COM2, adjustable CLASS 10/20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Solid":"2x (0.25 ... 1.5 mm²)","Width":"90 mm","at DC":"24 ... 24 V","title":"3RA6500-2AB43","Height":"191 mm","at 400 V":"53 kA","Trip Class":"CLASS 10 and 20 adjustable","Recommended":"vertical, on horizontal standard mounting rail","description":"SIRIUS Compact load feeder Reversing starter for IO-Link 690 V 24 V DC 0.1...0.4 A IP20 Connection main circuit: plug-in, without terminals Connection control circuit: Spring-type 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;
