It's a single-pole unit with a C-tripping characteristic, rated at 40 A with a maximum DC voltage of 72 V. ## Where it fits — panel and deployment Mounting position is any, so orientation in the enclosure is flexible. It's specified for residential buildings and infrastructure, but the DC rating makes it equally useful in industrial control cabinets for DC auxiliary circuits. The 72 V DC maximum at 40 A is the headline spec — this breaker protects a DC circuit up to that voltage and current, with a breaking capacity of 10 kA (per EN 60898, as the 5SL series is rated).","metaTitle":"Siemens 5SL5140-7CC SENTRON MCB, 1P C40 DC 72 V","metaDescription":"Siemens 5SL5140-7CC SENTRON miniature circuit breaker, 1-pole C-curve, 40 A DC rated at 72 V, 10 kA.

The difference is the current rating: 20 A vs. 40 A. It will physically fit in the same panel location, but the protection rating must match the circuit design."},{"question":"What is the depth of the 5SL5140-7CC?","answer":"The depth is 76 mm, with an installation depth of 70 mm. Width is 18 mm (one width unit on DIN rail), height is 90 mm."},{"question":"What compliance documentation is available for the 5SL5140-7CC?","answer":"The part is halogen-free and silicon-free. It carries an IP20 protection class (with connected conductors), overvoltage category III, and pollution degree 2. The 5SL series is typically certified to EN 60898 and IEC standards for miniature circuit breakers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL5140-7CC","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/5SL5140-7CC when reusing this data.
