It is designed for continuous operation per IEC 60947-6-2, meaning it handles sustained motor runs, not just jogging or inching duty. The adjustable trip class (Class 10 and 20) lets you match the overload curve to the motor's starting profile: Class 10 for faster-starting loads like pumps, Class 20 for higher-inertia loads like fans or conveyors that need a longer acceleration ramp. ## IO-Link integration This reversing starter supports IO-Link communication at COM2 (38.4 kBaud), so it reports motor current, trip status, and operating hours back to the controller. Five on-board LEDs give local status without needing to open the cabinet door — useful for a quick visual check during commissioning or fault-finding. The main circuit connection is plug-in without terminals — mates to a pre-wired base, which speeds panel assembly and reduces wiring errors. The control wiring accepts 2x (0.25 to 1.5 mm²) solid or stranded conductors. Mounts via screw or snap-on to a standard DIN rail. The recommended orientation is vertical on a horizontal mounting rail, though any position is permitted. Rated for pollution degree 3 (industrial environments with conductive or dry non-conductive pollution). Vibration resistance is 4 to 5.8 Hz at 15 mm amplitude, then 5.8 to 500 Hz at 20 m/s² for 10 cycles. Shock resistance is 60 m/s² (6g) for 10 ms, 3 shocks per axis.","metaTitle":"Siemens 3RA6500-2BB43 SIRIUS Compact Reversing Starter","metaDescription":"Siemens 3RA6500-2BB43 SIRIUS compact reversing starter with IO-Link, 24 VDC coil, adjustable Class 10/20, 53 kA at 400 V.
