The coil hold-in and dropout characteristics follow the standard SIRIUS contactor curve — expect reliable pick-up down to roughly 85% of rated voltage. The storage range of -55... +80 °C allows for cold warehouses without concern. Switching frequency limits are specified by duty class: 1 000 cycles/hour at AC-1 (resistive loads), 750 cycles/hour at AC-3 (motor starting/running), and 250 cycles/hour at AC-4 (plugging/inching). The auxiliary switch (built-in) provides rated values of 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. These are the DC-13 ratings for inductive loads — a common trap is assuming the 24 V figure holds at higher voltages. It does not; plan your control circuit accordingly. ## Mechanical Fit and Wiring The S0 frame size accepts main contact wiring of 1... 10 mm² solid or stranded, with dual-wire capability for 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). These are the minimum air gaps to adjacent metalwork or other devices — respect them to avoid flashover at rated voltages.","metaTitle":"Siemens 3RT2027-1NP30-ZX95 SIRIUS Power Contactor, S0, 200-2","metaDescription":"Siemens SIRIUS 3RT2027-1NP30-ZX95 power contactor, S0 size, 200-280V AC coil, screw terminals, 45mm wide, 107mm deep, active production, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"107 mm","Solid":"1 ... 10 mm²","Width":"45 mm","at AC":"30 ... 50 ms","at DC":"30 ... 45 ms","Height":"85 mm","Upwards":"10 mm","Forwards":"10 mm","Stranded":"1 ... 10 mm²","at 50 Hz":"0.51","at 60 Hz":"0.56","Downwards":"10 mm","Arcing Time":"10 ... 10 ms","At The Side":"6 mm","Rated Value":"200 ... 280 V","Initial Value":"0.7","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-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":"Yes","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","Full-Scale Value":"1.1","at AC-3e maximum":"750 1/h","For Main Contacts":"16 ... 8","Mounting Position":"+/-180° rotation possible on vertical mounting surface;
