Siemens 3RA2323-BXB30-1AC2 Reversing Contactor

Siemens SIRIUS 3RA2323-BXB30-1AC2 is a 3-pole reversing contactor assembly (SIRIUS 3RA23 family) used to reverse motor direction in AC circuits, with a compact form suitable for panel-mount motor control cabinets. It operates from a 24 V coil and uses screw-terminal connections in the Size S0 configuration, with an electrical and mechanical interlock that supports safe, interlocked operation during switching. The device supports AC-3e/AC-3 duty and includes two normally open auxiliary contacts (2 x NO) for signaling or interlocking in control circuits, enabling straightforward integration into standard motor starter circuits. It is rated for up to 690 V AC and carries a nominal current of 9 A, making it suitable for switching moderate-power motors in applications such as conveyors, pumps, or fans within machine control panels.
