Miniature circuit breaker 230 V 6kA, 1+N-pole, C, 3A
The Siemens 5SL6503-7CC is a miniature circuit breaker (MCB) rated 230 V with a 6 kA breaking capacity, 1+N-pole configuration, C-curve trip characteristic, and 3 A rated current. This is a standard DIN-rail mount device for final distribution boards in commercial and light industrial panels — the C-curve means it trips between 5 and 10 times rated current, sized for general-purpose loads like lighting circuits and small motor starters where inrush isn't extreme.
