Rated operational voltage is 400 V AC (440 V max single- or multi-phase), 50/60 Hz. IP20 with conductors connected; pollution degree 3 (conductive pollution typical of control rooms and light industrial floors). Sealable — panel builders can lock the toggle position after commissioning. ## Environmental and derating Ambient temperature range -40 °C to 75 °C, but relative humidity derates above 55 °C: max 95% RH at 55 °C, dropping to 55% at 70 °C and 35% at 75 °C. Current-production status per Siemens lifecycle data. The 5SY6206-6 carries dual-standard certification: EN 60898-1 (household-type MCB) and IEC 60947-2 (industrial MCB), plus UL 1077 / CSA C22.2 No. 235 for North American acceptance.

The difference is the tripping characteristic — the 5SY6206-6 is B-curve, while the 5SY4140-7 is a different curve or rating. Check the branch-circuit coordination study before swapping; the physical swap takes seconds."},{"question":"What compliance documentation does Siemens provide for the 5SY6206-6?","answer":"The MCB is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 / CSA C22.2 No. 235. It is halogen-free and silicon-free.
