Breaking capacity is 10 kA per both EN 60898 and IEC 60947-2 at 400 V AC, meaning it can safely interrupt a fault current up to that level without upstream cascading. The overvoltage category is III, suitable for fixed-installation distribution boards. ## Derating and real-world current At 40 °C it derates to 46.19 A, at 45 °C to 44 A, and at 55 °C to 39.81 A. ## Panel fit and environment Depth is 76 mm (installation depth 70 mm), height 90 mm, width 18 mm — one standard modular unit. Sealable with a lead seal for tamper-evident installations. Protection class is IP20 with connected conductors, plus touch protection on the terminals. Degree of pollution 2 (normal, non-conductive).","metaTitle":"Siemens SENTRON 5SL4150-7 MCB, 1P, 50 A, C-curve, 10 kA","metaDescription":"Siemens SENTRON 5SL4150-7 miniature circuit breaker, 1-pole, 50 A rated at 30 °C, C tripping characteristic, 10 kA breaking capacity per EN 60898 and IEC 60947-2.
