The unit is rated 20 A at 30 °C and carries a 10 kA breaking capacity per EN 60898 (20 kA per IEC 60947-2), so it handles typical domestic or light commercial fault levels without upstream coordination worries. ## Fit and derating At 36 mm wide and 77 mm deep (70 mm installation depth), this RCBO drops into a standard DIN-rail distribution board with IP20 protection once installed and conductors connected. The temperature derating is published: 20 A at 30 °C, 18.8 A at 40 °C, 16.2 A at 55 °C, down to 14.6 A at 70 °C — so if your panel runs hot, size the circuit accordingly.","metaTitle":"Siemens 5SU1354-0KK20 SENTRON RCBO, 2-pole B-curve 20 A, 10","metaDescription":"Siemens 5SU1354-0KK20 SENTRON RCBO, 2-pole (1P+N), B-curve, 20 A at 30 °C, 10 kA per EN 60898, 20 kA per IEC 60947-2, Type AC residual current, halogen-free, IP20, active productio","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"77 mm","Width":"36 mm","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Halogen-Free":"Yes","Silicon-Free":"Yes","Number Of Poles":"2","lifecycle_stage":"current","Mounting Position":"any","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"2","Operating Frequency":"50 Hz","Product Designation":"RCBO","acc. to IEC 81346-2":"F","at AC / rated value":"230/240 V","protection class IP":"IP20, if the distribution board is installed, with connected conductors","Overvoltage Category":"III","Design Of The Product":"Instantaneous","Residual Current Type":"AC","Number Of Poles / Note":"1P+N","acc. to DIN EN 61346-2":"F","Energy Limitation Class":"3","Weight / With Packaging":"271 g","at 30 °C / rated value":"20 A","at 40 °C / rated value":"18.8 A","at 45 °C / rated value":"18.2 A","at 50 °C / rated value":"17.4 A","at 55 °C / rated value":"16.2 A","at 60 °C / rated value":"16.2 A","at 65 °C / rated value":"15.4 A","at 70 °C / rated value":"14.6 A","Number Of Modular Width Units":"2","Tripping Characteristic Class":"B","acc. to EN 60898 / rated value":"10 kA","For Testing Equipment / Minimum":"195 V","Position / Of Power Supply Cord":"Either top or bottom","Number Of Poles / With Protection":"1","acc. to IEC 60947-2 / rated value":"20 kA","Product Feature / Touch Protection":"Yes","Tripping Fault Current / Rated Value":"30 mA","Supply Voltage Frequency / Rated Value":"50 Hz","Influence Of The Surrounding Temperature":"Max. 95% humidity","Surge Current Resistance / At (8/20) μS":"1 kA","operational current / at AC / rated value":"20 A","Product Function / Neutral Conductor Switching":"Yes","Mechanical Service Life (Switching Cycles) / Typical":"10 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/296de6eee324bb00708be5de46cd06da.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=183165&mlfb=5SU1354-0KK20","alternativesUrl":"https://aoctrl.com/api/mcp/products/5SU1354-0KK20/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 5SU1354-0KK20?","answer":"10 kA per EN 60898 and 20 kA per IEC 60947-2.
