The Siemens 3RT2325-1AV00 is a SIRIUS contactor in size S0, designed for switching loads on a 35 mm DIN rail per DIN EN 60715. It carries a single normally-open main contact rated 10 A at 230 V AC and 3 A at 400 V AC, with a mechanical endurance of 10 million operating cycles. The AC coil uses screw-type terminals, and the contactor accepts stranded wire from 1 to 10 mm² for the main circuit.
Mounting and integration
Mounts with screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5° — useful when you're fitting into a tight panel and need to angle the contactor for access. Dimensions are 85 mm high, 60 mm wide, 97 mm deep. Clearance: 10 mm upwards, downwards, forwards, and to the side.
Ratings and what they mean for your circuit
The main contact is rated for AC-1 resistive loads at 16 A and AC-3 motor switching at 8 A. That means it can handle a motor load up to about 4 kW at 400 V three-phase — enough for a small conveyor or pump. The auxiliary side has one instantaneous contact, so you get feedback or interlock without adding a separate block. Coil hold-in voltage is AC; the arcing time sits between 10 and 10 ms, which is tight enough for most coordination studies.
