At DC it's rated 15 kA per IEC 60947-2 up to 72 V, and under UL 1077 / CSA C22.2 No. 235 it carries 5 kA at AC. That UL/CSA rating means it's accepted in North American control panels as a supplementary protector, not a branch-circuit device. Rated voltage is 230 V AC single-phase (250 V for single-phase operation), with a maximum DC voltage of 72 V. The part is halogen-free and silicon-free, which is a spec that comes up when panels go into clean-room or semiconductor-adjacent environments where outgassing is restricted. Width is 36 mm (2 width units at 18 mm each), depth 76 mm, height 90 mm. Installation depth is 70 mm — that's the space needed behind the panel door, not counting the busbar or wiring. The 5SY6 design series is a mature line with broad acceptance across European and North American panel shops. The D-curve and 0.5 A rating are less common than the B or C variants at higher currents, so if you're filling a BOM line that calls for this exact code, the 1P+N configuration with neutral switching is the differentiator — a standard 2-pole MCB without neutral switching won't drop in functionally. Rated per EN 60898 and IEC 60947-2, with supplementary UL 1077 and CSA C22.2 No. 235 recognition. The part is halogen-free and silicon-free, and the product designation follows DIN EN 61346-2 and DIN EN 81346-2 functional identification (letter F). These standards cover the declaration pack a quality-documentation controller would need for panel traceability.","metaTitle":"Siemens 5SY6505-8 SENTRON MCB, 2-pole 0.5A D-curve, 6kA","metaDescription":"Siemens 5SY6505-8 SENTRON miniature circuit breaker, 0.5 A rated current, D tripping characteristic, 2-pole 1P+N, 6 kA per EN 60898, 30 kA per IEC 60947-2.

Volume pricing and availability are confirmed at quote time against an RFQ — no shelf stock is held, but the supply chain is active and the part is regularly specified into new builds."},{"question":"What is 5SY6505-8's listed depth (76 mm) on this component line?","answer":"The depth is 76 mm, with an installation depth of 70 mm. That 6 mm difference accounts for the front bezel overhang beyond the DIN-rail clip."},{"question":"What is 5SY6505-8's listed width (36 mm) on this component line?","answer":"Width is 36 mm, which is 2 width units at 18 mm per unit. Standard DIN-rail spacing, no special footprint."},{"question":"Will 5SY6505-8 drop into a panel that was specified around 5SY4140-7 without rewiring?","answer":"No — the 5SY6505-8 is a 1P+N configuration with neutral switching, while the 5SY4140-7 is a different pole count and characteristic. The footprint (width units) may differ, and the neutral switching function means the wiring topology is different. Check the specific pole configuration before substituting."},{"question":"What compliance documentation does this brand provide for 5SY6505-8 (RoHS, REACH, UL, IEC)?","answer":"The part carries ratings 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 halogen-free and silicon-free. Standard Siemens declaration of conformity and material compliance documentation is available through the supply chain."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY6505-8","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/5SY6505-8 when reusing this data.
