The Siemens SENTRON 5SY4105-7CC11 is a 1-pole miniature circuit breaker with C-curve tripping, rated 0.5 A at 400 V AC. Its 10 kA breaking capacity per EN 60898 means it will safely interrupt a fault current up to that level on a 400 V AC supply — enough for most distribution sub-mains and final circuits in industrial panels.
