Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, sufficient for most commercial and light industrial distribution boards where the prospective fault current stays under 5 kA. The Type A residual current detection handles pulsating DC faults — common from electronics, rectifiers, and variable-speed drives — not just sinusoidal AC leakage. The 77 mm depth and 90 mm height fit standard SENTRON distribution boards and enclosures. At 40 °C it derates to 30.4 A, at 50 °C to 28.8 A, and at 70 °C to 24.64 A. Size the upstream load for the actual ambient temperature. IP20 with connected conductors (the board enclosure provides the environmental seal). The 70 mm installation depth (into the board) and touch-protected terminals (finger-safe) meet the requirements of modern distribution boards.","metaTitle":"Siemens SENTRON 5SU1353-7KL32 RCBO, 32A C-curve, 2-pole, 4.5","metaDescription":"Siemens SENTRON 5SU1353-7KL32 RCBO, 32 A rated, C characteristic, 2-pole, 4.5 kA (EN 60898) / 5 kA (IEC 60947-2), Type A residual current, IP20, halogen-free, active lifecycle, ava","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":"32 A","protection class IP":"IP20, if the distribution board is installed, with connected conductors","Overvoltage Category":"III","Design Of The Product":"Instantaneous","Residual Current Type":"A","acc. to DIN EN 61346-2":"F","Energy Limitation Class":"3","Weight / With Packaging":"296 g","at 30 °C / rated value":"32 A","at 40 °C / rated value":"30.4 A","at 45 °C / rated value":"29.76 A","at 50 °C / rated value":"28.8 A","at 55 °C / rated value":"27.84 A","at 60 °C / rated value":"27.2 A","at 65 °C / rated value":"25.92 A","at 70 °C / rated value":"24.64 A","Number Of Modular Width Units":"2","Tripping Characteristic Class":"C","acc. to EN 60898 / rated value":"4.5 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":"5 kA","Product Feature / Touch Protection":"Yes","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","Influence Of The Surrounding Temperature":"Max. 95% humidity","Surge Current Resistance / At (8/20) μS":"1 kA","Type Of Voltage / Of The Operating Voltage":"AC","Product Component / 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/884b3174712398bae724029a7a57f6b5.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=472896&mlfb=5SU1353-7KL32","alternativesUrl":"https://aoctrl.com/api/mcp/products/5SU1353-7KL32/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1353-7KL32","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/5SU1353-7KL32 when reusing this data.
