The Siemens SENTRON 5SQ2570-2YA10 is a 2-pole miniature circuit breaker with a C-curve tripping characteristic, rated 10 A at 400 V AC and 50 Hz. It switches the neutral conductor as well as the line (1P+N), which matters for final circuits where you want the neutral isolated when the breaker trips — common in single-phase sub-distribution boards. The IP20 finger-safe terminals are fine inside a closed panel; no washdown rating here.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figures or lead-time numbers published here.
3 kA per EN 60898 at 400 V AC. That's the standard rating for this class — adequate for most final sub-circuits in residential and light commercial panels, but verify it coordinates with your upstream protective device.
Yes — it is a 1P+N design (2 poles total) that disconnects both the line and the neutral conductor. The product function explicitly includes neutral conductor switching.
No — the 5SU9304-1KK32 is an RCBO (RCD + MCB combo) with a 30 mA residual current trip and 10 kA breaking capacity, while the 5SQ2570-2YA10 is a plain MCB with 3 kA capacity and no earth-leakage protection. The form factor differs too: the RCBO is 1 width unit (18 mm), the MCB is 2 width units (36 mm). They are not drop-in interchangeable.
