For a panel fed from a transformer or a distribution board with a prospective fault current up to 6 kA, this MCB clears the fault without external fusing. The C-curve (5–10× In) is sized for moderate inrush loads — motor starters, small transformers, banks of LED drivers — where the magnetic trip must not nuisance-trip on startup. The 80 A rating on a 2-pole format suits larger subfeeds or high-current single-phase loads. ## Deployment context","metaTitle":"Siemens 5SY6280-7CC SENTRON MCB, 2P C 80A 6kA 400V","metaDescription":"Siemens SENTRON 5SY6280-7CC miniature circuit breaker, 2-pole, C-curve, 80 A rated, 6 kA breaking capacity per IEC 60947-2 at 400 V AC.
