The 18 mm width (1 modular unit) and 76 mm depth let it slot into standard DIN-rail enclosures without crowding adjacent breakers. The 63 A rating holds at 35 °C ambient. At 40 °C it derates to 59.16 A, at 50 °C to 55.06 A, and at 60 °C to 50.65 A. If the panel internal temperature runs hot — common in sealed railway enclosures or crowded cabinets — use the 50 °C figure for sizing, not the 35 °C headline. ## Sourcing and fit decision For a BOM line that previously specified the 5SY4140-7 (40 A version) or the 5SL6016-7KL (B-curve 16 A), the 5SY4163-7KK11 drops into the same 18 mm DIN footprint with the same 70 mm installation depth and combined terminal layout — no rewiring or enclosure change needed, just verify the 63 A rating matches the load and the C-curve magnetic trip suits the inrush.","metaTitle":"Siemens 5SY4163-7KK11 SENTRON MCB, 63A 1P C-Curve, 10kA","metaDescription":"Siemens SENTRON 5SY4163-7KK11 miniature circuit breaker, 63A, 1-pole, C characteristic, 10kA breaking capacity per EN 60898.
