The coil draws 0.25 A at 50 Hz and 0.28 A at 60 Hz — low enough for direct PLC output drive but verify the output's inrush capacity. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, with a mounting position that allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward. The envelope is 97 mm deep, 60 mm wide, and 102 mm high — compact for the S0 frame. The coil uses spring-type terminals, accepting 2x 0.5 to 2.5 mm² solid or stranded wire on the control side. Main circuit terminals accept 1 to 10 mm² stranded. The auxiliary switch is integral — no add-on module needed for basic status feedback. The auxiliary contact ratings span from 10 A at 24 V AC down to 0.1 A at 600 V AC — check your specific control voltage against the table to confirm the switching capacity.","metaTitle":"Siemens 3RT2325-2AC20 SIRIUS S0 Contactor, 24 V AC Coil, 18","metaDescription":"Siemens 3RT2325-2AC20 SIRIUS S0 contactor, 24 V AC coil 50/60 Hz, 18 A rated operational current, screw and snap-on DIN rail mount, current lifecycle stage, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"97 mm","Solid":"2x (0.5 ... 2.5 mm²)","Width":"60 mm","at AC":"4 ... 16 ms","Height":"102 mm","Upwards":"10 mm","Forwards":"10 mm","Stranded":"1 ... 10 mm²","at 50 Hz":"0.25","at 60 Hz":"0.28","Downwards":"10 mm","Attachable":"2","Arcing Time":"10 ... 10 ms","At The Side":"6 mm","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Spring-type terminals","Type Of Voltage":"AC","lifecycle_stage":"current","Auxiliary Switch":"Yes","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","For Main Contacts":"18 ... 8","Mounting Position":"+/-180° rotation possible on vertical mounting surface;
