D-curve means the magnetic trip operates at 10–20× rated current (100–200 A for this 10 A unit), sized for loads with high inrush — motor starters, transformers, solenoid banks — where a B or C curve would nuisance-trip on startup. The 1-pole form factor interrupts only the phase conductor — neutral stays solid — so it's right for single-phase branch circuits or three-phase groups where you need individual pole protection without switching the neutral. ## Temperature derating — the real-world current The 10 A rating holds at 35 °C. Above that, the continuous current must be reduced: 9.39 A at 40 °C, 9.07 A at 45 °C, 8.74 A at 50 °C, 8.4 A at 55 °C, and 8.04 A at 60 °C. If the panel ambient runs warm — say 50 °C inside an enclosed cabinet — the breaker is good for 8.74 A continuous, not the full 10 A. That derating curve is the number to use when sizing the branch circuit. Dual-rated to IEC/EN 60898-1 and IEC/EN 60947-2 / UL1077, so it qualifies for both household-type and industrial applications. IP20 with conductors connected. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SY7110-8 SENTRON MCB, 10 A, D Curve, 1P","metaDescription":"Siemens 5SY7110-8 SENTRON miniature circuit breaker, 10 A rated, D tripping characteristic, single pole, 15 kA per EN 60898.
