The Siemens SENTRON 5SY4610-6 is a 4-pole miniature circuit breaker (MCB) with a 3P+N pole design, B-curve tripping characteristic, and a 10 A rated current. It breaks faults at 10 kA per EN 60898-1 and 20 kA per IEC 60947-2 / UL 1077, covering both residential and industrial panel applications.
What the ratings mean for fit
The B-curve trips between 3 and 5 times rated current — 30 A to 50 A for this 10 A unit — making it a first-choice for resistive and general-purpose loads where inrush is moderate. The 10 kA breaking capacity under EN 60898-1 certifies it for final-distribution boards; the 20 kA rating under IEC 60947-2 gives headroom for industrial sub-distribution with higher prospective fault current. Four poles (3P+N) mean it switches all three phases plus the neutral, common in three-phase panelboards where neutral protection or isolation is required. The 4-module-width (72 mm) footprint fits standard DIN-rail enclosures; the quick-assembly fastening method and any mounting position simplify panel integration. Rated current derates with ambient temperature: 10 A at 35 °C, 9.52 A at 40 °C, down to 8.48 A at 60 °C. In a warm enclosure — say a packed panel at 50 °C — expect 9.02 A continuous capability. The IP20 rating (with connected conductors) is standard for enclosed distribution boards; the sealable option and touch protection suit installations requiring lockout or tamper resistance.
Compliance and documentation
The MCB is certified to IEC / EN 60898-1 and IEC / EN 60947-2 / UL 1077, covering both residential and industrial standards. It is halogen-free and silicon-free, with pollution degree 3 and overvoltage category III. The energy limitation class is 3, meaning it limits let-through energy effectively for downstream equipment protection.
