The Siemens 5SL4501-7CC is a SENTRON 5SL miniature circuit breaker, 1-pole+N, rated 1 A at 230 V AC with a C tripping characteristic and a 10 kA breaking capacity per EN 60898.
DIN-rail snap-on, any mounting position. Terminal accepts 0.75–25 mm² solid or stranded copper — the 25 mm² upper end is generous for a 1 A breaker, but useful when you're looping feed-through conductors from a larger upstream device. IP20 with conductors connected — fine for enclosed panels; keep it behind a locked door or gland plate.
