The 24 V coil draws 0.24 W holding power at both 50 and 60 Hz — a low enough draw that a standard 24 V control transformer can drive multiple contactors without sagging. Pollution degree 3 (conductive or dry non-conductive pollution) suits industrial environments where panels see dust and condensation. For coordination, Type 2 requires a 50 A gL/gG fuse; Type 1 allows up to 125 A — the difference is whether the contactor survives a fault or just clears it without welding. Side-by-side mounting is allowed with no derating gap — useful when packing multiple contactors in a tight row.","metaTitle":"Siemens 3RT7027-1AB00 S0 Contactor, 24 V 50/60 Hz, 3-Pole, 4","metaDescription":"Siemens 3RT7027-1AB00 SIRIUS S0 contactor, 24 V 50/60 Hz coil, 3-pole, 45 mm wide, IP20, screw terminals, current production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"91 mm","Width":"45 mm","Height":"85.5 mm","at 50 Hz":"0.24","at 60 Hz":"0.24","On The Front":"IP20","During Storage":"-25 ... +70 °C","Of The Terminal":"IP20","at AC-3 maximum":"800 1/h","at AC-4 maximum":"250 1/h","lifecycle_stage":"current","During Operation":"-10 ... +55 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 50022","at AC-3e maximum":"800 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)","Degree Of Pollution":"3","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 50 Hz rated value":"24 V","at 690 V rated value":"1 A","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-3 rated value maximum":"690 V","at AC-3e rated value maximum":"690 V","Insulation Voltage Rated Value":"690 V","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","With Type Of Assignment 2 Required":"gL/gG NH 3NA: 50 A","closing power of magnet coil at DC":"0.82 W","holding power of magnet coil at DC":"0.24 W","Surge Voltage Resistance Rated Value":"6 kV","With Type Of Coordination 1 Required":"gL/gG NH 3NA: 125 A","shock resistance with sine pulse at AC":"12.5g / 5 ms, 7.8g / 10 ms","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","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":"acceptability for PLC control (17 V, 5 mA)","Type Of Voltage Of The Control Supply Voltage":"AC","operational current at DC-13 at 220 V rated value":"0.3 A","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Required Spacing With Side-By-Side Mounting At The Side":"0 mm","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","number of NC contacts for auxiliary contacts instantaneous contact":"0","number of NO contacts for auxiliary contacts instantaneous contact":"0","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"6 mm²","Connectable Conductor Cross-Section For Auxiliary Contacts Finely Stranded With Core End Processing":"0.5 ... 2.5 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/38fc08985c6f19c90f44d3a8a91fb19c.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1533981&mlfb=3RT7027-1AB00","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT7027-1AB00/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 3RT7027-1AB00 and how is it quoted for volume purchases?","answer":"This part is sourced through independent distribution channels.
