The contact block carries 2 instantaneous NO contacts and 2 NC contacts, rated for AC-12 duty at 10 A maximum — that is the resistive load rating per IEC 60947-5-1, covering solenoid valves, indicator lamps, and PLC digital inputs. For inductive loads like contactor coils, derate to the AC-15 curve: at 230 V the rated value is 6 A, at 400 V it drops to 3 A, and at 690 V it is 1 A. The DC switching capability is present but limited: at 24 V rated value it handles 10 A, at 110 V only 1 A, and at 220 V just 0.27 A — so for DC motor brake or clutch circuits above 24 V, verify the load current against the curve. The depth is 73 mm, height 60 mm. Side clearance is 0 mm to adjacent devices, so it can be ganged directly without spacing. The screw terminals accept 2x solid conductors from 0.25 to 2.5 mm² — typical for control wiring in a 600 V panel. The front face carries IP20 finger protection, adequate for enclosed panels but not for open-rack mounting where tools or fingers could contact live parts.","metaTitle":"Siemens 3RH1122-2BB40-ZX96 SIRIUS Auxiliary Contactor, 10 A","metaDescription":"Siemens SIRIUS 3RH1122-2BB40-ZX96 auxiliary contactor, 10 A AC-12 max, 24 VDC coil, 2 NO + 2 NC contacts, screw/snap-on mount, 45 mm wide, current lifecycle status.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 mm","Maximum":"2 000 m","At The Side":"0 mm","Rated Value":"24 V","On The Front":"IP20","Initial Value":"0.8","Mounting type":"screw and snap-on mounting","During Storage":"-55 ... +80 °C","Leading Contact":"0","lifecycle_stage":"current","Auxiliary switch":"Yes","During Operation":"-25 ... +60 °C","During Transport":"-55 ... +80 °C","Full-scale value":"1.1","Shock resistance":"10g / 5 ms and 5g / 10 ms","Delayed Switching":"0","Lagging Switching":"0","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","Product brand name":"SIRIUS","Degree of pollution":"3","Product designation":"Auxiliary contactor","at 24 V rated value":"10 A","Of Contactor Typical":"30 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.27 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 500 V rated value":"2 A","at 690 V rated value":"1 A","Instantaneous Contact":"2","For Auxiliary Contacts":"0","Make-Before-Break Switching":"0","Closing power of magnet coil at DC":"3.2 W","Holding power of magnet coil at DC":"3.2 W","Operating current at AC-12 maximum":"10 A","Surge voltage resistance rated value":"6 kV","Reference code acc. to DIN EN 81346-2":"K","with low demand rate acc. to SN 31920":"40 %","with high demand rate acc. to SN 31920":"75 %","Finely Stranded With Core End Processing":"2x (0.25 ... 1.5 mm²)","at AWG conductors for auxiliary contacts":"2x (24 ... 14)","Contact reliability of auxiliary contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"Cage Clamp terminals","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","Of Auxiliary Contacts Instantaneous Contact":"0","Number of NC contacts for auxiliary contacts":"2","Number of NO contacts for auxiliary contacts":"2","with degree of pollution 3 at AC rated value":"690 V","Type of voltage of the control supply voltage":"DC","Identification number and letter for switching elements":"22 E","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","Of The Contactor With Added Electronics-Compatible Auxiliary Switch Block Typical":"5 000 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=177352&mlfb=3RH1122-2BB40-ZX96","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RH1122-2BB40-ZX96/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings for this auxiliary contactor?","answer":"The 3RH1122-2BB40-ZX96 has a 24 VDC coil drawing 3.2 W, 2 NO + 2 NC contacts rated 10 A AC-12 maximum, and AC-15 ratings of 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V.
