Depth is 96 mm, height 97 mm. That 96 mm depth is the body plus the screw terminals; ensure the enclosure has at least 110 mm clearance from the rail to the door or back wall for wiring access. Main circuit terminals are screw-type. They accept solid conductors: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²). Stranded: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²). That's enough for a 4 A motor circuit — typically 1.5 mm² or 2.5 mm² stranded is fine. The auxiliary switch terminals are transverse design and rated 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V — enough for a PLC input or a contactor coil, but check the inrush if driving a relay. ## Environment and endurance Shock rated at 25 g for 11 ms — survives typical panel vibration and transport drops. Mechanical endurance of the main contacts is 100,000 operations. Maximum switching frequency in AC-3 duty is 15 operations per hour — fine for a pump or fan start, not for a rapid-cycling application.","metaTitle":"Siemens 3RV1021-1EA15-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1EA15-ZW97 SIRIUS motor protection circuit breaker, 4 A continuous, CLASS 10 trip, 100 kA breaking at 400 V AC, phase failure detection, current production, availab","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 (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Width":"45 mm","Height":"97 mm","Maximum":"2 000 m","at 24 V":"1 A","at 60 V":"0.15 A","Stranded":"2x (1 ... 2.5 mm²), 2x (2.5 ... 6 mm²)","at 230 V":"0.5 A","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":"1.5 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":"100 kA","at AC at 500 V rated value":"100 kA","at AC at 690 V rated value":"6 kA","at AC-3 rated value maximum":"690 V","Of The Main Contacts Typical":"100 000","at AC in hot operating state":"7.25 W","Continuous current rated value":"4 A","Design of the auxiliary switch":"transverse","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":"2.4 W","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number of poles for main current circuit":"3","at AWG conductors for auxiliary contacts":"2x (18 ... 14)","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":"2.8 ... 4 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=404342&mlfb=3RV1021-1EA15-ZW97","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RV1021-1EA15-ZW97/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 3RV1021-1EA15-ZW97 at 400 V?","answer":"100 kA at 400 V AC.
