The 6 kA breaking capacity per EN 60898 covers most commercial and light industrial fault levels; for UL 1077 supplementary protection installations, the interrupting rating is 5 kA. At 40 °C the continuous current derates to 60.04 A, so a panel ambient above 35 °C needs a one-step upsizing consideration. The C-curve trips at 5–10× In, a good fit for general-purpose branch circuits feeding mixed resistive and inductive loads in mechanical engineering and industrial environments. Any mounting position is permitted, which simplifies layout in crowded enclosures.","metaTitle":"Siemens 5SY6463-7CC SENTRON MCB, 63A 4P C-Curve, 6kA","metaDescription":"Siemens SENTRON 5SY6463-7CC miniature circuit breaker, 63 A rated, 4-pole, C characteristic, 6 kA IEC breaking capacity.
