It switches the neutral conductor and fits into a standard 36 mm wide DIN-rail slot (2 width units). Terminals accept solid or stranded conductors from 0.75 to 25 mm²; tighten to 2.5–3 N·m. IP20 with the distribution board cover fitted — fine for indoor panels, not for wet locations. Rated for 50 Hz only. Overvoltage category 3 and energy limiting class 3 — standard for branch-circuit protection in final distribution.","metaTitle":"Siemens 5SL6520-6YA SENTRON MCB, 1P+N, B, 20 A, 6 kA","metaDescription":"Siemens SENTRON 5SL6520-6YA miniature circuit breaker, 1-pole+N, B-curve, 20 A, 6 kA breaking capacity per EN 60898.
