The phase failure detection built into the SIRIUS design adds a layer of protection for three-phase motors running on supply legs that may drop one phase. Screw-type terminals on the main current circuit accept solid conductors: 2x (0.5 … 1.5 mm²) and 2x (0.75 … 2.5 mm²). Stranded conductors: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²). The auxiliary switch is transverse design with its own terminal set. The IP20 rating on the front means the breaker is touch-safe for panel interiors but not suitable for washdown environments. Shock resistance is rated at 25g / 11 ms, which covers most industrial vibration environments. The mechanical endurance of the main contacts is typically 100 000 operations, and the maximum switching frequency in AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1021-1JA15-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1JA15-ZW96 SIRIUS motor protection circuit breaker, 10 A continuous, CLASS 10 trip, 100 kA breaking at 400 V, screw terminals, current lifecycle stage, available to","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":"4 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":"42 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":"9.25 W","Continuous current rated value":"10 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":"3.1 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":"7 ... 10 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=113251&mlfb=3RV1021-1JA15-ZW96","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RV1021-1JA15-ZW96/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 3RV1021-1JA15-ZW96 at 400 V?","answer":"100 kA at 400 V AC, which is the standard industrial distribution voltage for most panels."},{"question":"What trip class does this motor protection circuit breaker have?","answer":"CLASS 10, meaning it trips within 10 seconds at 7.2× rated current, matching standard induction motor startup characteristics."},{"question":"What wire sizes does the screw terminal accept?","answer":"Solid: 2x (0.5 … 1.5 mm²) and 2x (0.75 … 2.5 mm²).
