That 10 A figure is the thermal current — the continuous current the contacts can carry at the rated insulation voltage. For AC-15 inductive loads (solenoids, contactor coils), the switching current drops with voltage: 6 A at 230 V, 3 A at 400 V, 1 A at 690 V. So the 10 A headline applies at low-voltage control levels; at line voltage the contact rating is lower, and the AC-15 column is the one to size against. ## Mounting and wiring — snap-on DIN rail, spring terminals Snap-on mounting to a DIN rail — the 36 mm width and 47.7 mm depth fit a standard enclosure footprint. The auxiliary and control circuit connections use spring-loaded terminals, accepting 2x (0.5... 2.5 mm²) without core end processing or 2x (0.5... 1.5 mm²) with ferrules. AWG 20–14. No screw torque to check; the spring clamp holds the conductor against vibration. ## Contact configuration and service life Four normally-closed (NC) auxiliary contacts, designated 51/52, 61/62, 71/72, 81/82. The contact reliability is rated at one faulty switching per 100 million operations at 17 V, 1 mA — suitable for low-level signal switching in PLC feedback circuits. Mechanical service life is 10 million switching cycles typical. The leading and lagging switching contacts are both listed as 0, meaning no built-in time delay between contact sets. ## Insulation coordination and environmental limits Rated insulation voltage 690 V AC at pollution degree 3. Surge voltage resistance 6 kV. IP20 protection on the front — touch-safe for the panel interior but not washdown-rated. Operating temperature range -25 to +60 °C; storage -55 to +80 °C. The 6 kV surge rating means it coordinates with standard 400 V distribution panels without additional surge suppression on the control circuit.","metaTitle":"Siemens 3RH2911-2GA04-ZW96 SIRIUS Contactor Relay, 10 A","metaDescription":"Siemens 3RH2911-2GA04-ZW96 SIRIUS contactor relay, 10 A rated current, 4 NC auxiliary contacts, spring-loaded terminals, IP20 front.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Note":"with 3RH2","Depth":"47.7 mm","Width":"36 mm","title":"3RH2911-2GA04-ZW96","Height":"41.5 mm","Maximum":"10 A","at 24 V":"6 A","at 60 V":"2 A","at 110 V":"1 A","at 125 V":"6 A","at 220 V":"0.3 A","at 230 V":"6 A","at 250 V":"6 A","at 400 V":"3 A","description":"auxiliary switch, on the front, 4 NC, 51/52, 61/62, 71/72, 81/82, current path: 1 NC, 1 NC, 1 NC, 1 NC, spring-loaded terminal, physically coded, only with contactor relays 3RH2140 and 3RH2440 combinable (according to EN 50011), multi-unit packaging, pack = 196 units","During Storage":"-55 ... +80 °C","Leading Contact":"0","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"snap-on mounting","Lagging Switching":"0","Product Brand Name":"SIRIUS","Suitability For Use":"Contactor relay","at 24 V rated value":"10 A","at 60 V rated value":"4.7 A","at 110 V rated value":"3 A","at 220 V rated value":"1.2 A","at 440 V rated value":"0.5 A","at 600 V rated value":"0.26 A","Instantaneous Contact":"0","With Core End Processing":"2x (0.5 ... 1.5 mm²)","Without Core End Processing":"2x (0.5 ... 2.5 mm²)","at AC-15 at 690 V rated value":"1 A","protection class IP on the front":"IP20","Surge Voltage Resistance Rated Value":"6 kV","at AWG cables for auxiliary contacts":"2x (20 ... 14)","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","Mechanical Service Life (Switching Cycles) Typical":"10 000 000","Type Of Electrical Connection For Auxiliary And Control Circuit":"spring-loaded terminals","insulation voltage with degree of pollution 3 at AC rated value":"690 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5bd71f6835db4ddf3b375ffc14011297.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=496463&mlfb=3RH2911-2GA04-ZW96"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RH2911-2GA04-ZW96","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RH2911-2GA04-ZW96 when reusing this data.
