The AC-4 rating of 250 cycles per hour covers inching and plugging applications where the contactor breaks the motor at full load. The coil draws 0.24 A at both 50 Hz and 60 Hz, and the contactor is rated for a 24 VDC coil supply. Spring-type terminals on the magnet coil accept solid or stranded wire from 0.5 to 4 mm², with dual-wire capability (2x 0.5...4 mm²). The AC-3 switching frequency of 750 cycles per hour means this contactor can handle frequent motor starts in conveyor or pump applications without overheating. The auxiliary switch is listed as 'No' — this contactor ships without a built-in auxiliary contact block. If your circuit needs a feedback signal or interlock, you'll add a separate auxiliary switch block (Siemens SIRIUS 3RT19 series). ## Integration Notes These are minimum air gaps for heat dissipation and arc containment — don't cram it tighter in a dense panel. Wire termination: spring-type terminals accept 0.5 to 4 mm² solid or stranded, or 2x 0.5 to 4 mm². Strip length is not listed, but standard spring-clamp practice is 8-10 mm. No auxiliary contacts on board — plan for an add-on block if needed.","metaTitle":"Siemens 3RT2016-2AK64-3MA0 SIRIUS Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT2016-2AK64-3MA0 power contactor, size S00, 24 VDC coil, spring-type terminals, 0.5...4 mm² wire, 45 mm wide, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"121 mm","Solid":"0.5 ... 4 mm²","Width":"45 mm","at AC":"4 ... 15 ms","Height":"70 mm","Upwards":"10 mm","Forwards":"10 mm","Stranded":"0.5 ... 4 mm²","at 50 Hz":"0.24","at 60 Hz":"0.24","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"6 mm","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Spring-type terminals","at AC-1 maximum":"1 000 1/h","at AC-2 maximum":"750 1/h","at AC-3 maximum":"750 1/h","at AC-4 maximum":"250 1/h","lifecycle_stage":"current","Auxiliary Switch":"No","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","at AC-3e maximum":"750 1/h","For Main Contacts":"20 ... 12","Mounting Position":"+/-180° rotation possible on vertical mounting surface;
