The IP20 front means it's finger-safe for panel builders working live. ## Trip class and motor protection It includes phase failure detection, so if you lose a phase on a lightly loaded motor, the breaker trips rather than letting the motor single-phase and burn. Rated operating frequency is 15 operations per hour maximum at AC-3 duty, which covers most conveyor and pump starts but not frequent jogging or reversing cycles. Backwards clearance is 0 mm, so it can sit flush against the back panel. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrules. AWG equivalent is 2x (24 to 14). No screw torque to worry about — strip and push. Shock rated at 25g for 11 ms.","metaTitle":"Siemens 3RV1011-1CA20-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-1CA20-ZW97 SIRIUS motor protection circuit breaker, 2.5 A rated current, CLASS 10 trip, 0.75 kW at 400 V, 100 kA breaking capacity at 400 V, spring-loaded terminals","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Protection Circuit Breakers (MPCB)"],"specifications":{"Depth":"81 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"90 mm","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":"0.75 kW","Design Of The Product":"for motor protection","Ground Fault Detection":"No","Phase Failure Detection":"Yes","For Main Current Circuit":"spring-loaded 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":"10 kA","at AC at 690 V rated value":"2 kA","at AC-3 rated value maximum":"690 V","at AC in hot operating state":"7.25 W","Substance Prohibitance (Date)":"01.01.2013","Continuous Current Rated Value":"2.5 A","at AWG cables for main contacts":"2x (24 ... 14)","protection class IP on the front":"IP20","For Auxiliary And Control Circuit":"spring-loaded 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":"2.4 W","Finely Stranded With Core End Processing":"2x (0.25 ... 1.5 mm²)","Number Of Poles For Main Current Circuit":"3","Touch Protection Against Electrical Shock":"finger-safe","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","number of CO contacts for auxiliary contacts":"0","operational current at AC-3 at 400 V rated value":"2.5 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":"1.8 ... 2.5 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=70626&mlfb=3RV1011-1CA20-ZW97","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RV1011-1CA20-ZW97/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3RV1011-1CA20-ZW97 and get a price?","answer":"It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time."},{"question":"What is the trip class and what does it mean?","answer":"CLASS 10 means the breaker trips within 10 seconds at 7.2× the current setting, matching standard DOL motor starts."},{"question":"What is the breaking capacity at 400 V?","answer":"100 kA at 400 V AC, which is high enough for most industrial panels without needing upstream current-limiting fuses."},{"question":"Does it include phase failure protection?","answer":"Yes, phase failure detection is built in — it will trip if a phase is lost on a lightly loaded motor."},{"question":"What wire sizes does the spring terminal accept?","answer":"Solid: 2x (0.25 to 2.5 mm²); finely stranded with ferrule: 2x (0.25 to 1.5 mm²); AWG: 2x (24 to 14)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1011-1CA20-ZW97","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/3RV1011-1CA20-ZW97 when reusing this data.
