Ground fault detection is not included, so if that's required, an external ground-fault relay or a different variant would be needed. Main circuit terminals accept solid or stranded conductors: 2x (1 … 2.5 mm²) or 2x (2.5 … 6 mm²) per pole, AWG 2x (14 … 10). Screw-type terminals. Dimensions: 45 mm wide, 97 mm high, 96 mm deep. Zero clearance required at the sides or rear for ventilation (0 mm backwards, 0 mm at the side).","metaTitle":"Siemens 3RV1021-4BA10-ZI41W96 SIRIUS Motor Protection Circui","metaDescription":"Siemens 3RV1021-4BA10-ZI41W96 SIRIUS motor protection circuit breaker, 20 A continuous, 7.5 kW at 400 V, trip class 10, 50 kA breaking at 400 V, phase failure detection, DIN rail m","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Protection Circuit Breakers (MPCB)"],"specifications":{"Depth":"96 mm","Solid":"2x (1 ... 2.5 mm²), 2x (2.5 ... 6 mm²)","Width":"45 mm","Height":"97 mm","Maximum":"2 000 m","Stranded":"2x (1 ... 2.5 mm²), 2x (2.5 ... 6 mm²)","Backwards":"0 mm","Trip class":"CLASS 10","At The Side":"0 mm","Rated Value":"690 V","On The Front":"IP20","Mounting type":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","During Storage":"-50 ... +80 °C","at AC-3 maximum":"15 1/h","lifecycle_stage":"current","Auxiliary switch":"Yes","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Shock resistance":"25g / 11 ms","Mounting position":"any","Product brand name":"SIRIUS","Product designation":"circuit breaker","at 400 V rated value":"7.5 kW","Design of the product":"for motor protection","For Auxiliary Contacts":"0","Ground fault detection":"No","Phase failure detection":"Yes","For Main Current Circuit":"screw-type terminals","at AC at 240 V rated value":"100 kA","at AC at 400 V rated value":"50 kA","at AC at 500 V rated value":"10 kA","at AC at 690 V rated value":"4 kA","at AC-3 rated value maximum":"690 V","Of The Main Contacts Typical":"100 000","at AC in hot operating state":"10.5 W","Continuous current rated value":"20 A","at AWG conductors for main contacts":"2x (14 ... 10)","Surge voltage resistance rated value":"6 000 V","at AC in hot operating state per pole":"3.5 W","Finely Stranded With Core End Processing":"2x (1 ... 2.5 mm²), 2x (2.5 ... 6 mm²)","Number of poles for main current circuit":"3","For Auxiliary And Control Current Circuit":"screw-type terminals","Removable Terminal For Auxiliary And Control Circuit":"No","Design of the overcurrent release and short-circuit release":"thermomagnetic","Arrangement of electrical connectors for main current circuit":"front side","Adjustable pick-up value current of the current-dependent overload release":"14 ... 20 A"}},"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=153988&mlfb=3RV1021-4BA10-ZI41W96","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RV1021-4BA10-ZI41W96/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1021-4BA10-ZI41W96","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/3RV1021-4BA10-ZI41W96 when reusing this data.
