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.","metaTitle":"Siemens 5SQ2570-2YA32 SENTRON MCB, 2P C 32A, 3kA","metaDescription":"Siemens SENTRON 5SQ2570-2YA32 miniature circuit breaker, 2-pole, C-curve, 32 A, 3 kA breaking capacity per EN 60898, 400 V AC, 50 Hz, IP20, pollution degree 3.

This is the rated short-circuit capacity for the MCB under standard test conditions — suitable for final circuits where the prospective fault current stays at or below 3 kA."},{"question":"What does the C-curve mean on this MCB?","answer":"The C tripping characteristic (class C) means magnetic trip occurs between 5× and 10× In (160 A to 320 A for this 32 A unit). This handles moderate inrush from small motors, transformers, or capacitive loads without nuisance tripping while still clearing low-impedance faults quickly."},{"question":"Does 5SQ2570-2YA32 switch the neutral?","answer":"Yes, the product function includes neutral conductor switching — both poles (1P+N) open and close together.
