Rated for AC 400 V (phase-to-neutral) and DC 60 V, it carries a 10 kA breaking capacity under EN 60898-1 and 35 kA under IEC 60947-2 — enough headroom for most commercial and light-industrial fault levels without cascading upstream. One modular width (18 mm wide, 90 mm tall, 76 mm deep including the quick-assembly fastening system) — it clips onto the DIN rail and occupies the same slot as any standard 1P MCB. No special cutout or gland-plate adjustment needed. IP20 with conductors connected — safe for enclosed panels, not for wet-area installation. That 35 kA figure is the one you care about for panel SCCR calculations in an industrial setting — it means the breaker can interrupt a 35 kA prospective fault without rupturing. Also carries a UL 1077 listing at 5 kA (AC) for North American supplementary-protection applications — not a branch-circuit-rated breaker under UL 489, so verify the local code requirement before using it as a main disconnect. The DC rating (15 kA at 60 V per IEC 60947-2) covers DC bus protection in drives or battery circuits — useful if you're feeding a DC link from a rectifier. For BOM traceability, the manufacturer provides RoHS and REACH compliance documentation along with the IEC/EN/UL certifications. The sealable design (tamper-evident cover) supports inspection and LOTO procedures.","metaTitle":"Siemens 5SY4100-7 SENTRON MCB, 1P C-Curve 10kA, 400V AC","metaDescription":"Siemens 5SY4100-7 SENTRON miniature circuit breaker, 1-pole C-curve, 10 kA per EN 60898-1 / 35 kA per IEC 60947-2, 400 V AC.
