It also handles DC circuits — the type of voltage is AC/DC, so it can protect DC loads up to the rated current. With neutral conductor switching built in, this 2-pole unit breaks both phase and neutral, which is standard for final subcircuits where the neutral must be switched. ## Where it fits — panel and enclosure integration The 5SQ2270-2YA32 occupies 2 width units (18 mm per unit = 36 mm) on a DIN rail and has an installation depth of 55 mm. That shallow depth is a plus when the enclosure back wall is tight — it leaves more room for wiring and busbar connections than the 70 mm or 77 mm typical of RCBOs in the same SENTRON family.","metaTitle":"Siemens SENTRON 5SQ2270-2YA32 MCB, 2-pole, C-curve, 32 A, 3","metaDescription":"Siemens SENTRON 5SQ2270-2YA32 miniature circuit breaker, 2-pole, C-curve, 32 A, 3 kA breaking capacity per EN 60898, 400 V AC, IP20.

The 5SQ2270-2YA32 is a plain MCB with 3 kA breaking capacity and no RCD function, and its 55 mm depth is shallower. They are not drop-in interchangeable; the panel design and protection scheme differ."},{"question":"What compliance documentation does Siemens provide for 5SQ2270-2YA32?","answer":"As a SENTRON MCB rated per EN 60898, it carries CE marking for the European market. The manufacturer typically provides a declaration of conformity and, for specific orders, a certificate of conformance.
