It breaks 10 kA per EN 60898 and 15 kA per IEC 60947-2, so it handles fault levels up to that point without upstream coordination issues in a standard distribution board. The 50 A rating holds at 35 °C; above that the breaker derates linearly to 42.4 A at 60 °C. That matters if the panel runs hot — the actual trip threshold drops, so a continuous load near 50 A may nuisance-trip in a warm enclosure.","metaTitle":"Siemens 5SY4150-5 SENTRON MCB, 50 A, 1P, Characteristic A, 1","metaDescription":"Siemens 5SY4150-5 SENTRON miniature circuit breaker, 50 A, 1-pole, tripping characteristic A, 10 kA (EN 60898) / 15 kA (IEC 60947-2).
