Siemens 5SQ2570-2YA32 — SENTRON 2P MCB, C 32 A, 3 kA
The Siemens 5SQ2570-2YA32 is a SENTRON miniature circuit breaker (MCB) with 2 poles (1P+N), a C tripping characteristic, and a 32 A rated operating current at 400 V AC, 50 Hz. The neutral pole switches integrally — the product function includes neutral conductor switching — so this unit suits single-phase or split-phase panels where both line and neutral need isolation on overcurrent.
Energy limiting class 3 means it restricts let-through energy well enough to coordinate with downstream equipment in a selective scheme. The 55 mm installation depth and 2 width units (36 mm at standard 18 mm/module) fit standard DIN-rail enclosures — check gland plate depth if the panel is shallow.
Panel integration
IP20 with connected conductors — the front is finger-safe but the terminals require the panel cover for full protection. The 55 mm installation depth leaves clearance in most 80 mm deep enclosures; verify against the gland plate or backplate depth if the panel is tight. Supply voltage can be connected top or bottom; the neutral pole is switched, so mark the neutral bar accordingly.
