Its 3 kA breaking capacity per IEC 60947-2 at 230/400 V AC tells you it can safely interrupt a fault current up to 3 kA without welding contacts or cascading failure upstream. That is a standard residential / light-commercial SCCR level; for higher fault currents (e.g., 6 or 10 kA) you step up to the 5SL6 or 5SL4 series. Halogen-free and silicon-free construction — important for environments where outgassing could contaminate sensitive contacts or optics (e.g., clean rooms, medical equipment enclosures). For a BOM freeze or critical-spare holding, the 5SL1202-7MB is a safe line item — no imminent obsolescence risk.","metaTitle":"Siemens 5SL1202-7MB SENTRON MCB, 2A C-curve 2-pole, 3kA","metaDescription":"Siemens SENTRON 5SL1202-7MB miniature circuit breaker, 2A C-curve, 2-pole, 230/400V AC, 3kA breaking capacity per IEC 60947-2.
