The AC coil draws 27 VA pick-up power and 5.4 VA holding power at a power factor of 0.8 and 0.27 respectively, making it a standard choice for 24 V, 110 V, 220 V, 230 V, and 400 V control circuits where switching frequencies up to 1,000 operations per hour at DC-13 duty are required. Rated operational current spans 6 A at 24 V, 230 V, and 400 V, 1 A at 110 V and 690 V, and 0.3 A at 220 V — these values govern the contact rating for the specific voltage applied in the circuit. The 45 mm wide, 72 mm deep, 57.5 mm high footprint snaps onto a standard 35 mm DIN rail, with screw and snap-on fastening. Terminals accept 2 x (0.5…1.5 mm²), 2 x (0.75…2.5 mm²), or 2 x 4 mm² solid or stranded wire, and 2 x (0.5…1.5 mm²) or 2 x (0.75…2.5 mm²) finely stranded with ferrule — covering most control-circuit wiring in a standard panel. The 3RH7131-1AH00 is a current-production SIRIUS contactor relay, meaning it can be specified into new designs and ordered as needed for BOM replenishment or line-down replacements. Auxiliary contacts are rated for PLC control reliability at 17 V, 5 mA, meaning the relay can switch low-level signals typical of programmable logic controller inputs without contact oxidation issues. Surge voltage resistance is rated at 16 kV, and shock resistance is specified at 15g / 5 ms and 8g / 10 ms for sine pulse, and 10g / 5 ms and 5g / 10 ms for rectangular impulse — suitable for industrial environments with vibration. Operating temperature range is -10 to +55 °C during operation, with storage from -25 to +70 °C. Installation altitude is limited to 2,000 m above sea level.","metaTitle":"Siemens 3RH7131-1AH00 SIRIUS Contactor Relay, 3NO+1NC, AC Co","metaDescription":"Siemens SIRIUS contactor relay 3RH7131-1AH00, size S00, 3 NO + 1 NC auxiliary contacts, AC coil, screw terminals, IP20, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"72 mm","Width":"45 mm","title":"3RH7131-1AH00","Height":"57.5 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","description":"Contactor relay 3NO1NC AC 48V 50/60Hz size S00, screw terminal","During Storage":"-25 ... +70 °C","lifecycle_stage":"current","During Operation":"-10 ... +55 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail","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":"S00","Solid Or Stranded":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), 2x 4 mm²","Product Brand Name":"SIRIUS","Product Designation":"Contactor relay","at 24 V rated value":"6 A","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"6 A","at 50 Hz rated value":"48 V","at 60 Hz rated value":"48 V","at 690 V rated value":"1 A","protection class IP on the front":"IP20","Product Extension Auxiliary Switch":"Yes","Surge Voltage Resistance Rated Value":"16 kV","operating frequency at DC-13 maximum":"1 000 1/h","shock resistance with sine pulse at AC":"15g / 5 ms, 8g / 10 ms","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Contact Reliability Of Auxiliary Contacts":"acceptability for PLC control (17 V, 5 mA)","apparent holding power of magnet coil at AC":"5.4 VA","apparent pick-up power of magnet coil at AC":"27 VA","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"3","Type Of Voltage Of The Control Supply Voltage":"AC","shock resistance at rectangular impulse at AC":"10g / 5 ms, 5g / 10 ms","Inductive Power Factor With Closing Power Of The Coil":"0.8","Identification Number And Letter For Switching Elements":"31 E","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Inductive Power Factor With The Holding Power Of The Coil":"0.27","Type Of Electrical Connection For Auxiliary And Control Circuit":"screw-type terminals","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Design Of The Fuse Link For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d32e5f21b85d3ef7c273e992333d38ae.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1533818&mlfb=3RH7131-1AH00"},"ai":{"faq":[{"question":"Where can I buy 3RH7131-1AH00 and how do I get a price?","answer":"The 3RH7131-1AH00 is available to order.
