What it is and what it does
The Siemens 5SL4114-7CC is a 1-pole miniature circuit breaker (MCB) rated for 230/400 V AC with a 10 kA breaking capacity. The C-curve characteristic means it trips at 5 to 10 times rated current — suited for protecting circuits with moderate inrush, like small motor or lighting loads. At 0.3 A, this is a very low-current unit, typically used for control transformers, signal circuits, or instrumentation supplies where a standard 1 A or 2 A breaker would be too coarse.
