What This Part Is and Where It Fits
The Siemens SIRIUS 3RT2325-1AP00-ZX95 is a Size S0 contactor with a 230 V AC coil, designed for switching motor loads and resistive loads in industrial control panels. It mounts on 35 mm DIN rail per DIN EN 60715, using either screw fixing or snap-on clips.
Key Ratings and What They Mean
The main contacts are rated for 10 A at 230 V AC — this is the AC-1 resistive load rating, meaning it can handle a 10 A resistive heater or lighting bank continuously. For motor (AC-3) duty, the rating is lower; the contactor's frame size S0 typically handles up to about 5.5 kW at 400 V, but the exact AC-3 value is not listed in this spec set. The coil pulls 10 A inrush at 24 V, then holds at a lower sealed current. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. That covers most indoor panel environments and unheated warehouses. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt, so you can fit it in tight enclosures without derating.
Panel Integration Notes
The contactor is 60 mm wide, 85 mm high, 97 mm deep — a standard S0 footprint that fits alongside other SIRIUS S0 devices on the same DIN rail. The screw-type coil terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded wire. Main power terminals handle 1 to 10 mm² stranded. Clearance around the contactor: 10 mm upward/downward, 6 mm sideways for arc quenching. An auxiliary switch is included (1 NO + 1 NC instantaneous contact), so you don't need a separate add-on block for basic feedback to a PLC or status lamp.
