The type F detection handles mixed-frequency residual currents from variable-speed drives, washing machine inverters, and similar loads where type A would nuisance-trip on the high-frequency content. The 2-module-width (36 mm) body fits standard DIN-rail enclosures with a 77 mm depth — check the enclosure depth before specifying, as some shallow consumer units leave less than 80 mm behind the rail. ## Temperature derating and environmental limits Rated current is 40 A at 30 °C ambient, derating to 37.6 A at 40 °C, 36.4 A at 45 °C, 34.8 A at 50 °C, 32.4 A at 55 °C and 60 °C, and 30.8 A at 65 °C, down to 29.2 A at 70 °C. In a 40 °C panel — typical for a sealed outdoor enclosure in summer — the continuous load limit drops to 37.6 A, so a 40 A circuit feeding a continuous EV charger needs a higher-rated device or active ventilation.","metaTitle":"Siemens 5SU1354-4KK40 RCBO, Type F, 40 A, 30 mA, 10 kA","metaDescription":"Siemens SENTRON 5SU1354-4KK40 RCBO, 1P+N, 40 A rated, 30 mA type F residual current, 10 kA breaking capacity, C characteristic.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"77 mm","Width":"36 mm","title":"5SU1354-4KK40","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","description":"RCBO, 10 kA, 1P+N, type F, super-resistant K, 30 mA, C-Char, In: 40 A, Un AC: 230 V","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"1P+N","Number Of Poles":"2","lifecycle_stage":"current","Mounting Position":"any","at AC rated value":"40 A","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"2","Operating Frequency":"50/60 Hz","Product Designation":"RCBO","protection class IP":"IP20, if the distribution board is installed, with connected conductors","Overvoltage Category":"III","Design Of The Product":"Super resistant K","Residual Current Type":"F","Weight With Packaging":"293 g","at 30 °C rated value":"40 A","at 40 °C rated value":"37.6 A","at 45 °C rated value":"36.4 A","at 50 °C rated value":"34.8 A","at 55 °C rated value":"32.4 A","at 60 °C rated value":"32.4 A","at 65 °C rated value":"30.8 A","at 70 °C rated value":"29.2 A","Energy Limitation Class":"3","according to EN 61346-2":"F","according to IEC 81346-2":"F","For Testing Equipment Minimum":"195 V","Number Of Modular Width Units":"2","Position Of Power Supply Cord":"Either top or bottom","Tripping Characteristic Class":"C","Number Of Poles With Protection":"1","according to EN 60898 rated value":"10 kA","Tripping Fault Current Rated Value":"30 mA","insulation voltage (Ui) rated value":"264 V","Supply Voltage Frequency Rated Value":"50 Hz","Surge Voltage Resistance Rated Value":"4 000 V","according to IEC 60947-2 rated value":"15 kA","Surge Current Resistance At (8/20) μS":"3 kA","Influence Of The Surrounding Temperature":"Max. 95% humidity","Type Of Voltage Of The Operating Voltage":"AC","Mechanical Service Life (Switching Cycles) Typical":"10 000","for rated value of the current at AC in hot operating state per pole":"7.8 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$67.04","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/bdc8d6e4bcddd5e81d7590ead853945b.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=147500&mlfb=5SU1354-4KK40"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1354-4KK40","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/5SU1354-4KK40 when reusing this data.
