The 3-pole unit mounts on a 35 mm DIN rail per EN 50022 via screw and snap-on fastening, and accepts screw-type terminals for both main and auxiliary circuits — solid or stranded wire from 1 to 6 mm². The 100 kA breaking capacity at 400 V (and at 240 V, 500 V, and 690 V as well) means this breaker can safely interrupt a fault current up to that level without upstream fuses needing to clear first. The 45 mm width (3-module) fits standard enclosure spacing. Screw terminals accept 1 to 2.5 mm² (solid or stranded) for the main circuit, and 2.5 to 6 mm² as well — no special tooling needed. The auxiliary switch option (product extension available) shares the same terminal block.","metaTitle":"Siemens 3RV1021-0DA10-ZW95 SIRIUS Motor Protection Breaker,","metaDescription":"Siemens 3RV1021-0DA10-ZW95 SIRIUS motor protection circuit breaker, 0.32 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V, IP20 front, screw terminals, DIN rail mount","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","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","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Shock Resistance":"25g / 11 ms","Mounting Position":"any","Product Brand Name":"SIRIUS","Product Designation":"circuit breaker","at 400 V rated value":"0.09 kW","Design Of The Product":"for motor protection","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":"100 kA","at AC at 500 V rated value":"100 kA","at AC at 690 V rated value":"100 kA","at AC-3 rated value maximum":"690 V","at AC in hot operating state":"5.5 W","Substance Prohibitance (Date)":"01.05.2012","Continuous Current Rated Value":"0.32 A","at AWG cables for main contacts":"2x (14 ... 10)","protection class IP on the front":"IP20","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","operating frequency at AC-3 maximum":"15 1/h","Surge Voltage Resistance Rated Value":"6 000 V","at AC in hot operating state per pole":"1.8 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","Touch Protection Against Electrical Shock":"finger-safe","number of CO contacts for auxiliary contacts":"0","operational current at AC-3 at 400 V rated value":"0.32 A","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Design Of The Overcurrent Release And Short-Circuit Release":"thermomagnetic","Arrangement Of Electrical Connectors For Main Current Circuit":"front side","Product Component Removable Terminal For Auxiliary And Control Circuit":"No","Mechanical Service Life (Switching Cycles) Of The Main Contacts Typical":"100 000","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"0.22 ... 0.32 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=358994&mlfb=3RV1021-0DA10-ZW95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RV1021-0DA10-ZW95/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of this breaker at 400 V?","answer":"100 kA at 400 V AC, and the same rating applies at 240 V, 500 V, and 690 V — full-range high-interrupting capability."},{"question":"What wire sizes does the 3RV1021-0DA10-ZW95 accept?","answer":"Screw terminals accept 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²) for both solid and stranded wire, plus 2x (14 to 10 AWG)."},{"question":"Where can I buy 3RV1021-0DA10-ZW95 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
