The internal damping circuit limits inrush current on capacitor energisation, which a standard contactor would weld shut on. Screw-type coil terminals — no push-in or spring-cage option on this variant. Rated switching frequency tops out at 100 cycles per hour at 230–600 V, dropping to 72 cycles per hour at 690 V — this sets the capacitor bank cycling limit, not the contactor's thermal current. ## Panel fit — 45 mm width, S0 frame Width is 45 mm, height 135 mm, depth 155 mm — the S0 frame footprint. Stranded: 2×(1–2.5 mm²) or 2×(2.5–10 mm²). At 40 °C ambient, a single 10 mm² conductor is the maximum; at 60 °C, two 10 mm² conductors are allowed. One instantaneous NO auxiliary contact is built in — no additional auxiliary switch block attached (0 attachable auxiliary switches). ## Auxiliary contact ratings across voltages Arcing time is 10 ms typical, with AC switching between 4 and 16 ms. ## Environmental range and production status Sourced through authorized distribution channels.","metaTitle":"Siemens 3RT2627-1AP05 SIRIUS Capacitor Contactor","metaDescription":"Siemens 3RT2627-1AP05 SIRIUS capacitor contactor, size S0, 230 V AC 50 Hz coil, screw terminals, 45 mm wide, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"155 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), 2x 4 mm²","Width":"45 mm","at AC":"4 ... 16 ms","title":"3RT2627-1AP05","Height":"135 mm","at 24 V":"6 A","at 60 V":"2 A","Stranded":"2x (1 ... 2.5 mm²), 2x (2.5 ... 10 mm²)","at 110 V":"1 A","at 125 V":"0.9 A","at 220 V":"0.3 A","at 230 V":"6 A","at 400 V":"3 A","at 50 Hz":"0.8 ... 1.1","at 690 V":"1 A","at 40 °C":"1x 10 mm²","at 60 °C":"2x 10 mm²","Attachable":"0","Arcing Time":"10 ... 10 ms","description":"capacitor contactor, AC-6b 25 kVAr, / 400 V, 3-pole, 230 V AC, 50 Hz, auxiliary contacts: 1 NO + 2 NC, screw terminal, size: S0","1 Rated Value":"50 Hz","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","Type Of Voltage":"AC","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 50022","at 230 V maximum":"100 1/h","at 240 V maximum":"100 1/h","at 400 V maximum":"100 1/h","at 480 V maximum":"100 1/h","at 500 V maximum":"100 1/h","at 600 V maximum":"100 1/h","at 690 V maximum":"72 1/h","Mounting Position":"+/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface","Size Of Contactor":"S0","Solid Or Stranded":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), 2x 4 mm²","Product Brand Name":"SIRIUS","Product Designation":"capacitor contactors","at 50 Hz rated value":"230 V","Instantaneous Contact":"1","For Main Current Circuit":"screw-type terminals","Relative Humidity Minimum":"10 %","Of Main Circuit Rated Value":"6 kV","Substance Prohibitance (Date)":"05/01/2014","For Grounded Parts At The Side":"10 mm","Of Auxiliary Circuit Rated Value":"6 kV","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"No","at AC at 230 V maximum permissible":"7 mA","At Contactor For Auxiliary Contacts":"Screw-type terminals","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 2x 12","With Side-By-Side Mounting At The Side":"10 mm","Electrical Endurance (Operating Cycles)":"200 000","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number Of Poles For Main Current Circuit":"3","Contact Reliability Of Auxiliary Contacts":"0.00000001","mirror contact according to IEC 60947-4-1":"No","apparent holding power of magnet coil at AC":"9.8 VA","apparent pick-up power of magnet coil at AC":"77 VA","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"1","Type Of Voltage Of The Control Supply Voltage":"AC","contact rating of auxiliary contacts according to UL":"A600 / Q600","Inductive Power Factor With Closing Power Of The Coil":"0.82","Of Main Circuit With Degree Of Pollution 3 Rated Value":"690 V","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Inductive Power Factor With The Holding Power Of The Coil":"0.25","Of The Contactor With Added Auxiliary Switch Block Typical":"3 000 000","operational current of auxiliary contacts at AC-12 maximum":"10 A","Of Auxiliary Circuit With Degree Of Pollution 3 Rated Value":"690 V","For Short-Circuit Protection Of The Auxiliary Switch Required":"gG: 10 A (500 V, 1 kA)","AWG number as coded connectable conductor cross section for main contacts":"16 ... 8","For Short-Circuit Protection Of The Main Circuit With Type Of Coordination 1 Required":"gG: 80 A (690 V, 50 kA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$71.12","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/36dd2efac410d81a7399adb948b76e7c.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=46726&mlfb=3RT2627-1AP05"},"ai":{"faq":[{"question":"What wire sizes does 3RT2627-1AP05 accept?","answer":"Stranded: 2×(1–2.5 mm²) or 2×(2.5–10 mm²).
