The Siemens SENTRON 5SQ2270-2YA32 is a 2-pole miniature circuit breaker with a C-tripping characteristic, rated 32 A and breaking 3 kA at 400 V AC per EN 60898. 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.
