When populating a DIN-rail enclosure, account for the 1 MW (18 mm per pole) footprint and the 55 mm installation depth — the 5SQ series shares the same depth as the broader SENTRON family, so it lines up with adjacent busbars and terminal blocks. The IP20 finger-safe housing is standard for enclosed panels; no special washdown rating needed.","metaTitle":"Siemens 5SQ2170-2YA10 SENTRON MCB, 1-Pole C 10A, 3kA","metaDescription":"Siemens SENTRON 5SQ2170-2YA10 miniature circuit breaker, 1-pole, C-curve 10 A, 3 kA per EN 60898 at 240 V AC.
