It switches the neutral conductor alongside the line, so it's a single-module-width breaker that isolates both poles when it trips — no separate neutral bar needed in the distribution board. The 3 kA breaking capacity (per EN 60898 and IEC 60947-2) covers residential and light commercial fault levels; the C-curve (5 to 10 times rated current) handles motor inrush and lighting loads without nuisance tripping. Overvoltage category III means it's rated for fixed-installation mains (distribution level, not sub-distribution).","metaTitle":"SENTRON 5SQ2570-0KA32 MCB, 2-pole, C-curve, 32 A, 3 kA","metaDescription":"SENTRON 5SQ2570-0KA32 miniature circuit breaker, 2-pole (1P+N), C-curve, 32 A, 3 kA breaking capacity per EN 60898 & IEC 60947-2.

It's deeper (70 mm vs 55 mm) and wider (1 width unit vs 2).
