The B characteristic means the magnetic trip operates at 3 to 5 times rated current (120–200 A for this 40 A unit), making it the standard choice for resistive and general-purpose loads — lighting, socket circuits, control transformers — where inrush is modest. The 7.5 kA breaking capacity (Icn per EN 60898-1) tells you it can safely interrupt a fault current up to 7.5 kA at the rated voltage without welding contacts or cascading damage upstream. For a 40 A feeder in a commercial or light-industrial panel, that is adequate for most utility-side fault levels; if your available fault current exceeds 7.5 kA, step up to a 10 kA or 15 kA rated MCB in the same 5SL6 family.","metaTitle":"Siemens 5SL6240-6RC MCB 40A 2-pole B-curve 7.5kA","metaDescription":"Siemens 5SL6240-6RC miniature circuit breaker, 40 A, 2-pole, B characteristic, 7.5 kA breaking capacity.
