Status is Active per Siemens lifecycle data — this is a current-production catalog number, not a phase-out or NRND line. Breaking capacity of 6 kA at 400 V AC per EN 60898 means this breaker can safely interrupt a fault current up to 6,000 A. If your site's transformer is close and the PSCC exceeds that, step up to the 10 kA variant (e.g., 5SL4363-7). The DC rating tops out at 72 V — not a DC breaker for solar strings or battery banks. Factor this into panel thermal calculations if the board is densely populated. ## Installable Supplementary Devices The breaker accepts supplementary devices (shunt trip, undervoltage release, auxiliary contacts) — the product extension feature is enabled. This allows remote tripping or status feedback without replacing the base breaker.","metaTitle":"Siemens 5SL6263-7CC SENTRON MCB, 2P C 63A 400V 6kA","metaDescription":"Siemens SENTRON 5SL6263-7CC miniature circuit breaker, 2-pole, C-curve, 63 A, 400 V AC, 6 kA breaking capacity per EN 60898.
