The C-curve (tripping characteristic class C) means the magnetic trip fires at 5 to 10 times rated current — 30 to 60 A for this 6 A unit — which suits moderate inrush loads like DC power supplies, contactor coils, and small DC motors without nuisance tripping on startup. The 2-pole design switches both conductors, and the neutral conductor is not switched, so this is a line-to-line DC breaker, not a line-to-neutral device. ## Mounting and integration in a DC panel Mounting position is any, which helps when orienting the breaker in a crowded enclosure. The breaker is sealable for tamper-proofing in metering or critical circuits. The 5SY5206-7CC operates across a wide ambient temperature range from -40 °C to 75 °C, with humidity derating: max 95% RH up to 55 °C, tapering to 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 — sufficient for installation on machine-mounted panels or near rotating equipment. Supplementary devices such as auxiliary switches, shunt trips, or alarm contacts can be installed, allowing remote status indication or emergency tripping.","metaTitle":"Siemens 5SY5206-7CC SENTRON MCB, 2P C 6A, 440 VDC, 10 kA","metaDescription":"Siemens SENTRON 5SY5206-7CC miniature circuit breaker, 2-pole, C-curve, 6 A, 440 VDC, 10 kA breaking capacity per IEC 60947-2.

Submit an RFQ for current availability and pricing — confirmed at quote time."},{"question":"What is the closest functional alternative to 5SY5206-7CC?","answer":"The closest peer within the same SENTRON family is the 5SY5250-7, a 2-pole C-curve breaker rated for both AC and DC (400 VAC / 440 VDC) with a higher 15 kA DC breaking capacity per IEC 60947-2. The 5SY5206-7CC is DC-only and has a 10 kA DC rating. Both share the same 76 mm depth, 36 mm width, and DIN-rail mounting, so the 5SY5250-7 can drop into the same panel footprint if the application requires AC capability or a higher DC fault-current rating."},{"question":"Will 5SY5206-7CC drop into a panel specified around 5SY5250-7 without rewiring?","answer":"Yes. Both breakers share identical dimensions (76 mm depth, 36 mm width, 90 mm height), the same 2-pole form factor, and the same DIN-rail quick-assembly mounting. No rewiring of the panel layout is needed. The key difference is that 5SY5206-7CC is DC-only, while 5SY5250-7 handles both AC and DC."},{"question":"What compliance documentation is available for 5SY5206-7CC?","answer":"The breaker carries a DC rating per IEC 60947-2 (10 kA at 440 VDC). It is designed for pollution degree 3 and overvoltage category III. The product is halogen-free and silicon-free. For specific RoHS, REACH, or UL documentation, consult the Siemens SENTRON technical manual or request the declaration from your distributor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY5206-7CC","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/5SY5206-7CC when reusing this data.
