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.","metaTitle":"Siemens 5SY6463-7 SENTRON MCB, 63 A, 4-Pole, C-Curve","metaDescription":"Siemens SENTRON 5SY6463-7 miniature circuit breaker, 63 A rated, 4-pole, C tripping characteristic.

The 5SY6463-7 is a 63 A 4-pole C-curve MCB; the 5SY4116-6CC is a different rating and pole configuration. Both share the SENTRON platform and DIN-rail footprint, but the ampacity and coordination study must match — verify the existing device's rating before substituting."},{"question":"What compliance documentation does Siemens provide for 5SY6463-7?","answer":"The MCB is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL1077.
