It integrates a reversing contactor pair and overload protection in a single 90 mm wide unit that screws or snaps onto a standard mounting rail. Rated at 1.25 A at 400 V AC (370 W motor power) and controlled by a 24 V DC coil, this starter handles small reversing loads like conveyor drives, gate operators, or pump direction changes where space on the rail is tight. The adjustable trip class (Class 10 or 20) lets you match the thermal protection to the motor start profile — Class 10 for fast-starting pumps, Class 20 for high-inertia loads like fans or centrifuges. ## IO-Link and diagnostics This starter communicates via IO-Link at COM2 rate (38.4 kBaud), giving the controller access to current draw, thermal status, and fault codes through the 5 on-board LEDs for local indication. The plug-in main circuit connection (no terminals on the power side) keeps wiring clean — the control wiring lands on spring-cage terminals accepting 0.5 to 4 mm² solid or 2x 0.5 to 2.5 mm² ferruled conductors. Rated for pollution degree 3 environments, the 3RA6500-1BB43 operates from -20 to +60 °C and survives storage and transport from -55 to +80 °C. It handles 6g shock (10 ms, 3 shocks per axis) and vibration per the listed profile — suitable for machine-mounted panels near rotating equipment. The recommended mounting position is vertical on a horizontal rail, though any orientation is permitted.","metaTitle":"Siemens 3RA6500-1BB43 SIRIUS Compact Reversing Starter","metaDescription":"Siemens 3RA6500-1BB43 SIRIUS compact reversing starter with IO-Link, 24V DC coil, 1.25A at 400V.
