Rated current is temperature-dependent: 63 A at 35 °C, derated to 60.04 A at 40 °C, 58.46 A at 45 °C, 56.89 A at 50 °C, and 55.25 A at 55 °C. The part carries the SENTRON brand and is listed under IEC 81346-2 designation F (protective device). Suitability for operation is noted as mechanical engineering and industry — standard for a general-purpose MCB in industrial control panels. ## Integration and environmental notes Operating temperature range is -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz — adequate for machine-mounted panels near rotating equipment. Combined terminal top and bottom with touch protection on both sides.","metaTitle":"Siemens 5SY6463-8CC SENTRON MCB, 63 A, 4P, D Curve, 6 kA","metaDescription":"Siemens SENTRON 5SY6463-8CC miniature circuit breaker, 63 A rated, 4-pole, D tripping characteristic, 6 kA breaking capacity per EN 60898.

Verify the specific rating and tripping characteristic before substituting."},{"question":"What compliance documentation is available for 5SY6463-8CC?","answer":"The breaker carries IEC 60898 and UL 1077 / CSA C22.2 No.235 certifications. It is halogen-free and silicon-free, which supports RoHS and REACH compliance declarations."},{"question":"Where can I buy 5SY6463-8CC and get current pricing?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"Will 5SY6463-8CC fit a panel designed for 5SY6613-8 without rewiring?","answer":"Both are 4-module-width SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. However, the 5SY6463-8CC is a 63 A D-curve while the 5SY6613-8 is a different rating — verify the load current and trip coordination before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY6463-8CC","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/5SY6463-8CC when reusing this data.
