Reversing duty in a size S00 package
The Siemens 3RA2317-8XB30-1AB0 is a SIRIUS reversing contactor assembly — two mechanically interlocked contactors in a single size S00 housing, so it handles forward/reverse motor control without the panel space two separate contactors would eat. The 24 V 50/60 Hz coil matches common control transformer outputs.
Power and current across common line voltages
The mechanical interlock is proven — 10 million typical operating cycles on the contactor base, with a maximum switching rate of 750 operations per hour in AC-3 duty. That rate suits frequent reversing applications like conveyor shuttles or traverse drives.
Mounts on 35 mm DIN rail with a screw-and-snap-on fastening method — the screw secures the foot, the snap holds it under vibration.
What comes in the box — two identical contactors
The interlock is factory-fitted and tested; no field assembly of the mechanical bridge.
