Product details

The quick-assembly mounting system and any-position mounting orientation simplify panel layout — no derating needed for horizontal or inverted fit. 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.

Frequently asked questions

Where can I buy 5SY4206-8CC11 and how is it quoted?

The 5SY4206-8CC11 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 5SY4206-8CC11 drop into a panel specified around 5SY7140-8CC without rewiring?

Physically yes — both are 2-pole, 36 mm wide, DIN-rail mounted SENTRON breakers with the same terminal range (0.75 to 35 mm²). 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.

What compliance documentation does Siemens provide for 5SY4206-8CC11?

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. RoHS and REACH compliance is standard for current-production SENTRON products.
