This makes the 5SY4313-5 the correct choice for protecting semiconductor devices, control transformers, and sensitive electronic loads where a B- or C-curve would let through too much energy before opening. Rated 13 A at 35 °C ambient, the breaker derates to 11.39 A at 60 °C. ## Breaking capacity and fault clearing The DC rating under IEC 60947-2 is 15 kA, covering battery-backed DC bus circuits common in UPS and solar combiner panels.","metaTitle":"Siemens 5SY4313-5 SENTRON MCB, 3-Pole, 13 A","metaDescription":"Siemens 5SY4313-5 SENTRON 3-pole MCB, 13 A rated, A-characteristic for semiconductor protection. 10 kA (EN 60898) / 20 kA (IEC 60947-2) breaking capacity.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["3-Pole MCB (DIN Rail)"],"specifications":{"Depth":"76 mm","Width":"54 mm","title":"5SY4313-5","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","description":"Miniature circuit breaker 400 V 10kA, 3-pole, A, 13 A, D=70 mm","Halogen-Free":"Yes","Silicon-Free":"Yes","Number Of Poles":"3","Type Of Voltage":"AC","lifecycle_stage":"current","Fastening Method":"Quick assembly system","Mounting Position":"any","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"3","Product Designation":"Miniature circuit breaker","acc. to IEC 81346-2":"F","at AC / rated value":"13 A","protection class IP":"IP20, with connected conductors","Overvoltage Category":"III","Combined Terminal Top":"Yes","Number Of Poles / Note":"3P","acc. to DIN EN 61346-2":"F","at 35 °C / rated value":"13 A","at 45 °C / rated value":"12.22 A","at 50 °C / rated value":"11.95 A","at 55 °C / rated value":"11.67 A","at 60 °C / rated value":"11.39 A","Combined Terminal Bottom":"Yes","Suitability For Operation":"Mechanical engineering / industry","Number Of Modular Width Units":"3","Tripping Characteristic Class":"A","acc. to EN 60898 / rated value":"10 kA","Position / Of Power Supply Cord":"Any","acc. to IEC 60947-2 / rated value":"20 kA","Product Feature / Touch Protection":"Yes","Supply Voltage Frequency / Rated Value":"50/60 Hz","Influence Of The Surrounding Temperature":"max. 95% to 55°C, max. 55% to 70°C, max. 35% to 75°C","at DC / acc. to IEC 60947-2 / rated value":"15 kA","at AC / acc. to UL 1077 and CSA C22.2 No.235":"5 kA","vibration resistance / acc. to IEC 60068-2-6":"±1mm at 5 to 25Hz; 50m/s² at 25 to 150Hz","Product Function / Neutral Conductor Switching":"No","with multi-phase operation / at AC / rated value":"440 V","operating voltage / at DC / rated value / maximum":"72 V","with single-phase operation / at AC / rated value":"440 V","Mechanical Service Life (Operating Cycles) / Typical":"10 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$251.51","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/54ede573774b29ede5f25dd70234a1f3.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=232270&mlfb=5SY4313-5"},"ai":{"faq":[{"question":"Does the Siemens 5SY4313-5 have a sealable cover?","answer":"Yes, the breaker is sealable — the toggle can be locked with a wire seal or padlock for lockout/tagout compliance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY4313-5","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/5SY4313-5 when reusing this data.
