The 2-pole design switches both conductors simultaneously, which matters for DC applications where polarity is critical — the listing notes to consider polarity when connecting the supply cord. The wide ambient range from -40 °C to 75 °C covers outdoor cabinets in cold climates and hot machine compartments, but the current-carrying capacity derates above 35 °C: 47.5 A at 40 °C, 46.2 A at 45 °C, 44.9 A at 50 °C, and 43.5 A at 55 °C. If your BOM calls for a 50 A circuit at 35 °C but the panel ambient runs 50 °C, this breaker still delivers 44.9 A — enough headroom for most continuous loads, but verify against your actual load current. This MCB is designed for mechanical engineering and industry applications (acc. to IEC 81346-2 designation F). The product is sealable (can be locked in OFF position for LOTO compliance), and touch protection is built in. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — suitable for mounting on machinery with moderate vibration.","metaTitle":"Siemens 5SY5250-7CC SENTRON MCB, 2P C-50A DC 440V","metaDescription":"Siemens 5SY5250-7CC SENTRON miniature circuit breaker, 2-pole, C-curve, 50A at 35°C, rated DC 440V, 10kA breaking capacity.

The physical dimensions (76 mm depth, 90 mm height) are identical, so it fits existing enclosures and busbar arrangements without rewiring."},{"question":"How do I get current pricing and availability for 5SY5250-7CC?","answer":"We source and quote this part to order against an RFQ through our independent distribution channel. Availability and current pricing are confirmed at quote time — submit an RFQ and we'll respond with a firm price and lead time. No stock figures or price lists are published here because market conditions change daily."},{"question":"What compliance documentation does Siemens provide for 5SY5250-7CC?","answer":"The product is halogen-free and silicon-free, and carries the SENTRON brand designation. It is designed per IEC 60947-2 for DC breaking capacity and IEC 60068-2-6 for vibration resistance. Standard Siemens documentation includes a CE declaration of conformity and the product datasheet. For specific RoHS/REACH declarations or UL listing certificates, request them with your RFQ — we can pull them from the manufacturer's document portal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY5250-7CC","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/5SY5250-7CC when reusing this data.
