That 10 kA rating means it can safely interrupt a fault current up to that level without welding its contacts or cascading the fault upstream — critical for selectivity in a distribution panel. The B-curve (3–5× In) is the standard choice for resistive and general-purpose loads; it will hold through a mild inrush but trip fast on a hard short. ## Where it fits This MCB snaps onto a DIN rail via the quick-assembly system, occupies a single modular width of 18 mm, and can be mounted in any position. The depth of 76 mm and installation depth of 70 mm mean it sits flush in a standard 18 mm wide slot with no extra clearance needed behind the rail. IP20 with connected conductors is normal for a panel-mounted breaker — it's protected against finger contact but expects to live inside an enclosure.","metaTitle":"Siemens 5SY4104-6CC11 SENTRON MCB, 1P B-Curve 4A, 10kA","metaDescription":"Siemens SENTRON 5SY4104-6CC11 miniature circuit breaker, 1-pole, B-curve, 4A rated, 10kA breaking capacity per EN 60898.
