That C-curve means it trips between 5 and 10 times rated current, so it's sized for moderate inrush loads like small lighting circuits or control transformers where you don't want nuisance trips from a motor start but still need fast short-circuit clearance. The 6 kA rating tells you it can safely interrupt a fault current up to that level at 400 V without welding its contacts or cascading upstream — enough for most residential and light commercial panels. ## How it fits in the panel Snaps onto a standard DIN rail — one modular unit wide at 18 mm, depth 76 mm, installation depth 70 mm. Mounts in any position, so you're not fighting orientation in a tight enclosure. Rated IP20 only with connected conductors, meaning it's for inside a panel, not out in the washdown zone. Pollution degree 2 and overvoltage category III cover normal industrial and residential environments where you get occasional transient spikes but not conductive grime. ## Thermal derating you need to know The 1.6 A rating is at 30 °C ambient. At 40 °C it derates to 1.52 A, at 45 °C to 1.47 A, and at 55 °C to 1.4 A. If your panel runs hot — say next to a drive cabinet or in a sun-baked enclosure — size up one rating step so the MCB doesn't trip on a warm day under a normal load. The mechanical service life is 10 000 switching cycles, which is typical for a residential-grade breaker; it's not a switching device for frequent motor starts.","metaTitle":"Siemens 5SL6115-7 SENTRON MCB, 1P C-curve 1.6 A, 6 kA","metaDescription":"Siemens 5SL6115-7 SENTRON miniature circuit breaker, 1 pole, C-curve, rated 1.6 A at 30 °C, 6 kA breaking capacity per IEC 60898.

The 6 kA breaking capacity at 400 V covers most distribution board faults."},{"question":"Where can I buy the 5SL6115-7?","answer":"The 5SL6115-7 is sourced and quoted to order against an RFQ through independent distribution.

The difference is the trip curve (C vs B) and the current rating (1.6 A vs 32 A), so the protective coordination upstream must be re-evaluated."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6115-7","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/5SL6115-7 when reusing this data.
