Terminal capacity accepts solid or stranded conductors from 0.75 to 35 mm², with a tightening torque of 2.5 to 3.5 N·m. ## D-curve and breaking capacity The D tripping characteristic means the magnetic trip operates at 10 to 20 times the rated current (60 to 120 A for this 6 A unit), making it suitable for loads with high inrush currents — typically motor circuits, transformers, or solenoid banks where a B- or C-curve would nuisance-trip on startup. Overvoltage category III covers fixed-installation distribution boards. The part is also rated for DC circuits up to 72 V, which is useful for control-voltage taps in the same panel. Humidity tolerance is specified: max 95% at 55 °C, derating to 55% at 70 °C and 35% at 75 °C. The design conforms to EN 60898 for breaking capacity and carries the F designation per DIN EN 61346-2 and DIN EN 81346-2 for circuit-function identification.","metaTitle":"Siemens 5SY4206-8CC11 SENTRON MCB, 6A D-curve 2P 10kA","metaDescription":"Siemens 5SY4206-8CC11 SENTRON miniature circuit breaker, 6 A rated, D tripping characteristic, 2-pole, 10 kA breaking capacity at 400 V AC.

However, the 5SY4206-8CC11 is rated 6 A versus 40 A for the 5SY7140-8CC, so the circuit protection would be mismatched. Do not substitute without recalculating the load and cable sizing."},{"question":"What compliance documentation does Siemens provide for 5SY4206-8CC11?","answer":"The breaker is designed per EN 60898 (breaking capacity 10 kA at 400 V AC) and carries the F designation per DIN EN 61346-2 and DIN EN 81346-2. It is halogen-free and silicon-free. Standard Siemens documentation includes a CE declaration of conformity and the manufacturer's datasheet.
