The C-curve means it trips between 5 and 10 times rated current — standard for general-purpose loads like lighting, small motor circuits, and socket outlets where moderate inrush is expected. The 6 kA SCCR at 230/400 V AC tells you it can safely interrupt a fault up to that level without upstream damage in a residential or light commercial distribution board. ## Deployment and panel fit Snaps onto DIN rail in any mounting position, occupying a single modular width (18 mm). Depth of 76 mm and installation depth of 70 mm keep it inside standard distribution enclosures. IP20 with connected conductors means it's suitable for enclosed panels — not for wet or outdoor locations without a weatherproof enclosure. The housing is halogen-free and silicon-free, which matters for fire safety and for environments where silicone outgassing could contaminate sensitive equipment.","metaTitle":"Siemens 5SL6163-7 SENTRON MCB, 1P C 63 A 6 kA","metaDescription":"Siemens 5SL6163-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 63 A, 6 kA breaking capacity per EN 60898.
