It breaks fault currents up to 10 kA per EN 60898 at 400 V AC — the standard for residential and light commercial distribution panels. 50 A at 400 V AC is the continuous current per phase — this breaker protects a 50 A feeder or submain. The 10 kA breaking capacity (Icn) per EN 60898 means it can safely interrupt a short-circuit fault up to 10,000 A at the rated voltage; that covers most residential and light commercial service entrances where the prospective fault current stays under that threshold. The B-curve (3–5× In) avoids nuisance trips on lighting or resistive loads but will trip faster than a C-curve on moderate inrush. Terminal capacity accepts solid or stranded conductors from 0.75 to 25 mm², with a tightening torque of 2.5 to 3 N·m — enough for 25 mm² tails on a 50 A feed. ## Deployment context Ambient temperature range -25 to +55 °C operating, with storage from -40 to +75 °C. Halogen-free and silicon-free construction suits environments where outgassing must be minimized (data centers, clean manufacturing).","metaTitle":"Siemens 5SL4450-6CC SENTRON MCB, 4P, 50 A, B-Curve, 10 kA","metaDescription":"Siemens 5SL4450-6CC SENTRON miniature circuit breaker, 4-pole, 50 A, B tripping characteristic, 10 kA breaking capacity per EN 60898, 400 V AC.
