At 230 V AC, the 1.6 A rating governs the continuous load; the breaker clears faults at 6 kA per EN 60898 for standard domestic/commercial duty, and up to 30 kA per IEC 60947-2 for industrial panels where fault current is higher. That dual rating is the key: if your panel SCCR is above 6 kA, the 30 kA IEC rating keeps you coordinated without upsizing to a larger frame. The combined top and bottom terminals mean you can feed from either direction without rotating the breaker — saves time on a crowded DIN rail. Depth is 76 mm, width 36 mm (2 width units), height 90 mm; installs in any position, ambient -25 to +55 °C, storage -40 to +75 °C. IP20 with connected conductors, overvoltage category III. ## Panel integration note The 36 mm width (2 width units) fits standard enclosure cutouts. Sealable, so you can lock the toggle position for safety lockout/tagout. Touch protection is built in, so no extra finger-safe covers needed on the terminals.","metaTitle":"Siemens SENTRON 5SY6515-8 MCB, 1.6 A, D Curve, 2-Pole","metaDescription":"Siemens SENTRON 5SY6515-8 miniature circuit breaker, 1.6 A rated current, D tripping characteristic, 2-pole 1P+N, 230 V AC, 6 kA (EN 60898) / 30 kA (IEC 60947-2).

Availability and current pricing are confirmed at quote time through independent distribution channels. This is an active-production part, so lead times are generally standard for the class."},{"question":"What is 5SY6515-8's depth?","answer":"The depth is 76 mm. Width is 36 mm (2 width units), height is 90 mm. Installation depth is 70 mm — the extra 6 mm accounts for the toggle overhang."},{"question":"What wire sizes does 5SY6515-8 accept?","answer":"Solid and stranded conductors from 0.75 mm² up to 35 mm². The combined top and bottom terminals accept the full range at both ends, so you can feed-through or loop without extra connectors."},{"question":"Will 5SY6515-8 drop into a panel specified around 5SY4140-7 without rewiring?","answer":"Mechanically yes — same DIN-rail footprint, same 36 mm width, same terminal style accepting 0.75–35 mm². Electrically no — verify the load current and trip curve. The 5SY6515-8 is a 1.6 A D-curve; if the original 5SY4140-7 was a different rating or curve, the protection coordination changes. Rewiring is not needed, but re-verification of the protective device sizing against the load is mandatory."},{"question":"What compliance documentation does Siemens provide for 5SY6515-8?","answer":"The breaker carries approvals per EN 60898 (6 kA), IEC 60947-2 (30 kA AC, 15 kA DC), and UL 1077 / CSA C22.2 No.235 (5 kA). It is rated overvoltage category III. The SENTRON series is RoHS and REACH compliant per Siemens standard declarations. Specific certificates (CE, UKCA, EAC) are available on request with the RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY6515-8","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/5SY6515-8 when reusing this data.
