The B tripping characteristic (3–5× In) is specified for the DC circuit, so the magnetic trip thresholds are calibrated for DC fault profiles, not AC. The 6 A rating at 35 °C is the reference point; per the datasheet, the continuous current derates to 5.32 A at 40 °C, 4.95 A at 45 °C, 4.55 A at 50 °C, and 4.1 A at 55 °C — the thermal curve governs real-world panel loading, not the 35 °C number alone. The quick assembly system means it snaps onto the rail without tools. ## Environmental and compliance profile The sealable design allows the panel builder to lock the toggle position with a padlock or wire seal, preventing unauthorized switching during maintenance lockout procedures. Operating temperature range spans -40 °C to 75 °C, with humidity influence specified: max 95% RH up to 55 °C, derating to 55% RH at 70 °C and 35% RH at 75 °C. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — suitable for installation on machinery or conveyors with moderate vibration profiles.","metaTitle":"Siemens 5SY5206-6CC SENTRON MCB, 2P B 6A 440V DC 10kA","metaDescription":"Siemens 5SY5206-6CC SENTRON miniature circuit breaker, 2-pole, B-curve, 6A at 35°C, 440V DC, 10kA DC breaking capacity.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial response."},{"question":"What is 5SY5206-6CC's listed depth (76 mm) on this component line?","answer":"The overall depth is 76 mm, with an installation depth of 70 mm. The 6 mm difference accounts for the front projection of the toggle and terminal covers."},{"question":"What is 5SY5206-6CC's listed width (36 mm) on this component line?","answer":"The width is 36 mm, which corresponds to 2 modular width units on a standard DIN-rail panel. This is the same footprint as the 5SY5240-7 and other 2-pole SENTRON 5SY breakers."},{"question":"Will 5SY5206-6CC drop into a panel that was specified around 5SY5240-7 without rewiring?","answer":"Yes, it drops into the same DIN-rail slot — same 36 mm width, same 2 MW footprint, same terminal layout. No rewiring is needed. The only difference is the continuous current rating: 6 A at 35 °C for the 5SY5206-6CC versus a higher rating for the 5SY5240-7."},{"question":"What compliance documentation does this brand provide for 5SY5206-6CC (RoHS, REACH, UL, IEC)?","answer":"The breaker is designed to IEC 60947-2 for DC breaking capacity (10 kA at 440 V DC) and carries the SENTRON brand from Siemens. The halogen-free and silicon-free construction supports RoHS and REACH compliance requirements. For specific UL listing or country-specific certification documents, the manufacturer's declaration package is available on request."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY5206-6CC","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/5SY5206-6CC when reusing this data.
