Siemens SENTRON 5SY6463-7 — 63 A, 4-Pole MCB, C-Curve
It breaks fault currents up to 6 kA per EN 60898-1 and 10 kA per IEC 60947-2, giving it a higher interrupting rating under the industrial standard — the figure that governs SCCR coordination in a UL 508A panel is the 10 kA at the listed overvoltage category III. At 40 °C ambient the continuous rating derates to 59.98 A, and at 50 °C to 56.83 A — so if the panel runs hot, size the upstream protection for the derated figure, not the 63 A nameplate.
Depth is 76 mm (70 mm installation depth), which fits standard distribution enclosures.
Listed as current-production lifecycle stage. The part carries approvals per IEC / EN 60898-1, IEC / EN 60947-2, and UL1077 — covering both residential (EN 60898) and industrial (IEC 60947) application scopes. Suitable for mechanical engineering and industry environments per the manufacturer's classification.
