It carries a C tripping characteristic — the standard choice for moderate inrush loads like contactor coils, small DC motors, and control transformers where the startup surge is a few times the rated current but not extreme. That rating governs the available fault current the breaker can handle on a DC bus — if your panel's prospective short-circuit current exceeds 10 kA at the breaker terminals, you need a current-limiting device ahead of it or a higher-rated unit. Width is 18 mm (one modular unit), depth 76 mm, height 90 mm. The terminals are combined (top and bottom), accepting conductors for the rated current without needing a separate busbar adapter for the line side.","metaTitle":"Siemens 5SY5163-7CC SENTRON MCB, 1P C 63A DC 220V 10kA","metaDescription":"Siemens 5SY5163-7CC SENTRON miniature circuit breaker, 1-pole, C-curve, 63A rated at 220V DC, 10kA breaking capacity per IEC 60947-2.
