That means you get mechanical interlocking and the coil wiring already done — no risk of a mis-wired interlock on site, and no extra DIN rail space for a separate mechanical interlock module. The coil pulls 24 V at 50/60 Hz (cite:,). That's a standard control voltage for most PLC outputs and control transformers — no oddball voltage to stock separately. Two instantaneous auxiliary contacts are built in (cite:). If your reversing application needs a third aux for a status feedback or a mechanical brake, you'll need to add a side-mount auxiliary block. ## Mounting and wiring — fits where a single contactor lives The S0 footprint is 90 mm wide by 101 mm tall by 97 mm deep (cite:,) — about the same as one-and-a-half standard contactors, not two. That's the whole point: a reversing pair in the space of a single oversized contactor. Wire terminations are screw-type on both the main circuit and the coil (cite:,). The main power terminals accept 2x (1 … 2.5 mm²) solid or 2x (2.5 … 10 mm²) solid (cite:). For stranded wire, the range is 2x (0.5 … 1.5 mm²) or 2x (0.75 … 2.5 mm²) (cite:). ## Environmental and mechanical — built for panel life Storage spec goes from -55 to +80 °C (cite:). That covers most indoor industrial panels without derating. The contactor base is rated for 10 million mechanical operations (cite:). Shock resistance is 11.8 g / 5 ms and 7.4 g / 10 ms on AC; 15 g / 5 ms and 10 g / 10 ms on DC (cite:,).","metaTitle":"Siemens 3RA2324-8XB30-1AC2 Reversing Contactor, 24 V Coil","metaDescription":"Siemens SIRIUS reversing contactor assembly 3RA2324-8XB30-1AC2. 24 V 50/60 Hz coil, 5.5 kW at 400 V, 2 NO/NC aux contacts.
