The Size S0 frame (45 mm wide) fits standard 45 mm DIN-rail slots, with 50 mm clearance required above and below for thermal dissipation and arc venting. Fastening method accepts M4 screws for main contacts. Any mounting position is permitted. Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the side — zero forwards or backwards clearance needed, so it can sit flush against a backplate. Terminals accept 2× (1 to 2.5 mm²) solid or stranded, or 2× (2.5 to 10 mm²). Screwdriver shaft diameter 5 to 6 mm, Pozidriv size 2 tip. The S0 frame depth is 97 mm, width 45 mm, height 97 mm.","metaTitle":"Siemens 3RV2021-0HA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2021-0HA10-ZX95 SIRIUS motor protection circuit breaker, Size S0, Trip Class 10, 100 kA breaking capacity at 400 V, phase failure detection, screw and snap-on DIN rail m","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Protection Circuit Breakers (MPCB)"],"specifications":{"Depth":"97 mm","Width":"45 mm","title":"3RV2021-0HA10-ZX95","Height":"97 mm","Upwards":"50 mm","Forwards":"0 mm","Backwards":"0 mm","Downwards":"50 mm","Trip Class":"CLASS 10","At The Side":"30 mm","Rated Value":"20 ... 690 V","description":"Circuit breaker size S0 for motor protection, Class 10 A-release 0.55...0.8 A N-release 10 A Screw terminal Standard switching capacity Reusable packaging Pack = 43 units","During Storage":"-50 ... +80 °C","at AC-3 maximum":"15 1/h","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","at AC-3e maximum":"15 1/h","For Main Contacts":"M4","Mounting Position":"any","Solid Or Stranded":"2x (1 ... 2.5 mm²), 2x (2.5 ... 10 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Circuit breaker","at 230 V rated value":"0.1 kW","at 240 V rated value":"100 kA","at 400 V rated value":"100 kA","at 480 V rated value":"0.8 A","at 500 V rated value":"100 kA","at 600 V rated value":"0.8 A","at 690 V rated value":"100 kA","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","Design Of Screwdriver Shaft":"Diameter 5 to 6 mm","Size Of The Circuit-Breaker":"S0","Size Of The Screwdriver Tip":"Pozidriv size 2","at AC-3 rated value maximum":"690 V","Of The Main Contacts Typical":"100 000","at AC in hot operating state":"7.25 W","at AC-3 at 400 V rated value":"0.8 A","at AC-3e rated value maximum":"690 V","Of Auxiliary Contacts Typical":"100 000","Substance Prohibitance (Date)":"10/01/2009","at AC-3e at 400 V rated value":"0.8 A","Design Of The Overload Release":"thermal","Operating Frequency Rated Value":"50 ... 60 Hz","Operational Current Rated Value":"0.8 A","Design Of The Short-Circuit Trip":"magnetic","for AWG cables for main contacts":"2x (16 ... 12), 2x (14 ... 8)","Product Extension Auxiliary Switch":"Yes","Relative Humidity During Operation":"10 ... 95 %","Display Version For Switching Status":"Handle","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"2.4 W","With Side-By-Side Mounting At The Side":"0 mm","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (1 ... 2.5 mm²), 2x (2.5 ... 6 mm²), 1x 10 mm²","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","with low demand rate according to SN 31920":"50 FIT","For Main Contacts With Screw-Type Terminals":"2 ... 2.5 N·m","with high demand rate according to SN 31920":"50 %","number of CO contacts for auxiliary contacts":"0","number of NC contacts for auxiliary contacts":"0","number of NO contacts for auxiliary contacts":"0","shock resistance according to IEC 60068-2-27":"25g / 11 ms","Electrical Endurance (Operating Cycles) Typical":"100 000","Size Of Contactor Can Be Combined Company-Specific":"S00, S0","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Arrangement Of Electrical Connectors For Main Current Circuit":"Top and bottom","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"10 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"0.55 ... 0.8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/69e3aae776a3a972c11948ccacc118a3.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=35060&mlfb=3RV2021-0HA10-ZX95"},"ai":{"faq":[{"question":"Where can I buy 3RV2021-0HA10-ZX95 and get a price?","answer":"The part is sourced to order against an RFQ through independent distribution.
