Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 — the higher figure applies when the breaker is specified under the industrial standard, giving you a safety margin for fault currents up to 15 kA at the panel's supply side. The B-curve means the magnetic trip activates at 3–5× rated current — so 189–315 A instantaneous trip. Current derating is published across the ambient range: 63 A at 35 °C, 59.98 A at 40 °C, 58.4 A at 45 °C, 56.83 A at 50 °C, 55.12 A at 55 °C, and 53.42 A at 60 °C. If your panel ambient runs above 40 °C, the 40 °C figure (59.98 A) is the one to use for sizing — not the 35 °C headline. Four poles in a 72 mm wide housing — 4 modular-width units. Rated for mechanical engineering and industry, snaps onto a DIN rail via quick-assembly system, mountable in any position. Installation depth is 70 mm. IP20 with connected conductors — that's the usual protection for inside a panel. The terminals are combined top and bottom, meaning you can feed from either direction, and the supply cord can enter from any position. Touch protection is built in. Halogen-free and silicon-free construction, plus sealable — useful for environments where outgassing or tampering is a concern.","metaTitle":"Siemens 5SY4463-6KK11 SENTRON MCB, 4P B-curve 63 A, 10/15 kA","metaDescription":"Siemens SENTRON 5SY4463-6KK11 miniature circuit breaker, 4-pole, B-curve, 63 A rated, 10 kA (EN 60898) / 15 kA (IEC 60947-2), IP20, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Miniature Circuit Breakers (MCB)"],"specifications":{"Depth":"76 mm","Width":"72 mm","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","Halogen-Free":"Yes","Silicon-Free":"Yes","Number Of Poles":"4","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":"63 A","protection class IP":"IP20, with connected conductors","Overvoltage Category":"III","Combined Terminal Top":"Yes","Design Of The Product":"For railway applications","Number Of Poles / Note":"4P","acc. to DIN EN 61346-2":"F","Energy Limitation Class":"3","at 35 °C / rated value":"63 A","at 40 °C / rated value":"59.98 A","at 45 °C / rated value":"58.4 A","at 50 °C / rated value":"56.83 A","at 55 °C / rated value":"55.12 A","at 60 °C / rated value":"53.42 A","Combined Terminal Bottom":"Yes","Suitability For Operation":"Mechanical engineering / industry","Number Of Modular Width Units":"4","Tripping Characteristic Class":"B","acc. to EN 60898 / rated value":"10 kA","Position / Of Power Supply Cord":"Any","acc. to IEC 60947-2 / rated value":"15 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":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=55953&mlfb=5SY4463-6KK11","alternativesUrl":"https://aoctrl.com/api/mcp/products/5SY4463-6KK11/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY4463-6KK11","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/5SY4463-6KK11 when reusing this data.
