This is the Italian-market version of the unit. The B-curve characteristic means the breaker trips at 3 to 5 times rated current (150–250 A), which suits resistive and general-purpose loads where inrush is modest — think lighting circuits, small heaters, or control transformers. The 6 kA breaking capacity at 400 V tells you it can safely interrupt a fault current up to 6,000 A without welding its contacts or cascading failure upstream.","metaTitle":"Siemens 5SL6650-6BB Miniature Circuit Breaker, 50 A, B Curve","metaDescription":"Siemens 5SL6650-6BB miniature circuit breaker, 400 V, 6 kA, 3+N-pole, B characteristic, 50 A.
