The adjustable trip Class 10 and 20 lets you match the thermal overload curve to the motor's starting profile — Class 10 for shorter start times like fans or pumps, Class 20 for higher-inertia loads like conveyors or crushers. ## IO-Link and control integration IO-Link protocol is built in at COM2 (38.4 kBaud), giving the PLC direct access to the starter's diagnostic data — trip status, current draw, thermal capacity utilization — over a standard M12 cable, no analog or discrete I/O card needed. The 5 on-board LEDs provide local status indication for power, communication, and fault conditions, useful during commissioning and troubleshooting. Control voltage is 24 V DC, which is standard for modern PLC cabinets; the coil dissipation is 2.9 W at rated voltage, so thermal rise in a dense panel is manageable. Width is 90 mm, height 170 mm, depth 165 mm — fits a standard 90 mm-wide DIN-rail slot; stacking multiple units side-by-side is straightforward. Shock-rated at 60 m/s² (6 g) for 10 ms, three shocks per axis, and vibration-rated per the listed profile — suitable for installation on machinery or conveyors with moderate mechanical stress. Main circuit connections are plug-in without terminals — the mating plug accepts solid conductors from 0.5 to 4 mm², or two conductors from 0.5 to 2.5 mm² each, which covers standard motor wiring up to the 4 A rating.","metaTitle":"Siemens 3RA6500-1CB43 SIRIUS Compact Reversing Starter, 4 A","metaDescription":"Siemens 3RA6500-1CB43 SIRIUS compact reversing starter, 4 A at 400 V AC, adjustable Class 10/20, IO-Link COM2.
