The Siemens 5SL4515-7 is a SENTRON miniature circuit breaker (MCB) — a 1P+N unit rated 1.6 A at 230 V AC, with a C tripping characteristic and a 10 kA breaking capacity certified to both EN 60898 and IEC 60947-2. The 1P+N configuration switches the phase and switches the neutral, so it provides overcurrent protection on the line and isolates the neutral when the breaker is off — a common requirement for single-phase final circuits in many European and Asian panel standards.
Rated for ambient temperatures from -40 °C to +75 °C, with derated current values above 30 °C: 1.54 A at 40 °C, 1.5 A at 45 °C, 1.43 A at 55 °C (–). Halogen-free and silicon-free construction reduces toxic smoke and corrosive outgassing in a fire — a consideration for public buildings and data-center sub-distribution.
