Compared to a B-curve (3–5× In) or C-curve (5–10× In) MCB, the D-curve tolerates the brief, high starting currents of transformers, DC power supplies, and solenoid valves without nuisance tripping. For a 2 A rated breaker, the magnetic trip threshold sits between 20 A and 40 A — that is the window where a short-circuit or heavy overload will clear, but a normal motor start will pass. EN 60898 certifies the breaker for overcurrent protection in household and similar installations; the railway-design variant (5SY4202-8CC11) adds vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) and a wider operating temperature range of -40 °C to 75 °C, which are not found on standard commercial MCBs.","metaTitle":"Siemens SENTRON 5SY4202-8CC11 MCB, 2-pole D 2A, 400V 10kA","metaDescription":"Siemens SENTRON 5SY4202-8CC11 miniature circuit breaker, 2-pole, D-curve, 2A, 400V AC, 10kA breaking capacity per EN 60898.

Availability and current pricing are confirmed at quote time; volume pricing is handled per inquiry."},{"question":"Will 5SY4202-8CC11 drop into a panel specified around 5SY4101-7CV without rewiring?","answer":"Both are 2-pole SENTRON MCBs on the same DIN-rail footprint (36 mm width, 2 MW), so the mechanical fit is identical. The difference is the tripping characteristic: 5SY4202-8CC11 is a D-curve (2 A), while 5SY4101-7CV is a different curve and rating. Verify the load's inrush profile and the required breaking capacity before swapping — the D-curve tolerates higher inrush than a B or C curve, which may or may not match the original design intent."},{"question":"What compliance documentation does this brand provide for 5SY4202-8CC11?","answer":"The manufacturer provides RoHS and REACH declarations on request. The EN 60898 certification covers the 10 kA breaking capacity at 400 V AC. The railway-design variant includes documented vibration resistance per IEC 60068-2-6 and a -40 °C to 75 °C operating temperature range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY4202-8CC11","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SY4202-8CC11 when reusing this data.
