The 3RA2323-8XB30-1AC2 is a Siemens SIRIUS reversing contactor assembly — two mechanically interlocked contactors in one package that reverse a three-phase motor without needing external interlocks. Size S0 frame with screw-type terminals for both the main current circuit and the magnet coil.
Ratings that drive the fit
AC-3 rated at 4 kW (400 V) and 7.5 kW (690 V) — this covers most standard three-phase induction motors in the 4–7.5 kW band. At 480 V the current rating is 7.6 A; at 600 V it is 9 A. The coil terminals are screw-type, same as the main circuit. Mechanical life is 10 million operating cycles typical for the contactor — the reversing assembly itself is rated for 1 000 switching operations per hour maximum in AC-3 duty.
Mounting and wiring notes
Dimensions: 97 mm deep, 90 mm wide, 101 mm high. The S0 frame fits standard panel layouts; clearance requirements are 6 mm upwards, forwards, downwards, and to the side, with 0 mm backwards. The assembly includes one supplied contactor (3RT2023-1AK60) per direction of rotation — two contactors total, mechanically interlocked to prevent simultaneous closure.
