The B-curve means it trips between 3 and 5 times rated current — suited for resistive and general-purpose loads where inrush is moderate, not for high-surge motor circuits. The 10 kA interrupting rating at 400 V is the fault current it can safely clear without welding contacts or cascading damage upstream in the distribution panel.","metaTitle":"Siemens 5SY4140-6CC11 MCB, 1-pole B 40A, 10kA, railway","metaDescription":"Siemens 5SY4140-6CC11 miniature circuit breaker, 230/400 V, 10 kA, 1-pole, B-curve, 40 A.
