Breaking capacity is 15 kA per IEC/EN 60947-2, which covers most industrial panel fault levels up to that threshold. At 35 °C ambient it carries the full 10 A; derate to 8.89 A at 40 °C, 7.6 A at 50 °C, and 6.91 A at 55 °C — plan your grouping and ventilation accordingly. Width is 18 mm (1 modular unit), depth 76 mm, height 90 mm.","metaTitle":"5SY4110-8CV Siemens MCB, 1P D 10 A, 15 kA IEC 60947-2","metaDescription":"Siemens 5SY4110-8CV miniature circuit breaker, 1-pole D-curve 10 A, 15 kA breaking capacity per IEC/EN 60947-2.

Availability and current pricing are confirmed at quote time."},{"question":"What is the difference between 5SY4110-8CV and 5SY4110-7CV?","answer":"Both are 1-pole 10 A MCBs; the 8CV uses a D tripping curve (10–20× In), while the 7CV uses a C curve (5–10× In). The D curve suits motor and transformer loads; the C curve is for general-purpose distribution. They share the same 18 mm width, 76 mm depth, and 15 kA breaking capacity — so the 8CV drops into a panel wired for the 7CV without rewiring, but the trip behavior changes."},{"question":"What compliance documentation does Siemens provide for 5SY4110-8CV?","answer":"The breaker is designed to IEC/EN 60947-2, halogen-free and silicon-free.
