The 3-pole construction switches all three phases simultaneously, so it fits three-phase sub-circuits in residential or light infrastructure panels. Snaps onto standard DIN rail — 3 width units (54 mm wide) — and accepts conductors from 0.75 mm² up to 25 mm², which covers both control wiring and power feed-through in a distribution board. The D-curve's magnetic trip threshold (10–20× In) means it holds through the inrush of a small control transformer or a 0.25 kW motor starting direct-on-line, but still clears a hard short. Rated frequency is 50 Hz; maximum multi-phase voltage is 440 V AC.","metaTitle":"Siemens 5SL4301-8CC SENTRON MCB, 3-pole D 1 A, 10 kA","metaDescription":"Siemens 5SL4301-8CC SENTRON miniature circuit breaker, 3-pole, D-curve, 1 A rated, 10 kA breaking capacity per EN 60898 at 400 V AC.
