It is rated for 440 V AC (single- or multi-phase) and 72 V DC maximum, at 50/60 Hz. The B-curve trips between 3 and 5 times rated current, making it a standard choice for general-purpose branch-circuit protection in commercial and industrial panels — not for motor-starting inrush, but fine for lighting, receptacle, and control-transformer circuits. ## Breaking Capacity & Standards Compliance This breaker carries a 15 kA rating per IEC/EN 60898-1 (the domestic and light-commercial MCB standard) and a 40 kA rating per IEC 60947-2 (the industrial circuit-breaker standard). The 40 kA figure means it can safely interrupt high fault currents in industrial panels without upstream fuses — useful when the available fault current at the panel is above 15 kA. For UL 1077 and CSA C22.2 No. 235 applications, the rating is 5 kA. The part also meets pollution degree 3 and overvoltage category III, so it is suitable for fixed installations in enclosures where conductive contamination is possible. The 5SY7206-6 is halogen-free and silicon-free, which matters for panels in clean-room, semiconductor, or food-processing environments where outgassing or silicone contamination must be avoided. ## Panel Integration & Mounting The breaker snaps onto a DIN rail (35 mm) using the quick-assembly system and occupies 2 modular width units (36 mm). Mounting position is any, so it can be installed horizontally or vertically without derating. The IP20 rating applies with connected conductors — standard for enclosed panel use. Combined terminals at top and bottom accept the same wire range, simplifying wiring. Depth is 76 mm (installation depth 70 mm), leaving clearance behind the DIN rail. ## Environmental Range & Derating The 5SY7206-6 operates from -40 °C to 75 °C, with humidity derating: max 95% RH at 55 °C, tapering to 35% RH at 75 °C. That covers most indoor industrial panels and even unheated outdoor enclosures in temperate climates. The sealable feature allows the installer to lock the toggle position with a padlock for lockout/tagout compliance.","metaTitle":"Siemens 5SY7206-6 SENTRON MCB, 2-Pole, B-Curve, 15/40 kA","metaDescription":"Siemens 5SY7206-6 SENTRON miniature circuit breaker, 2-pole, B characteristic, 15 kA (EN 60898-1) / 40 kA (IEC 60947-2).

The 5SY7206-6 uses a B-curve; the 5SY4116-6CC uses a C-curve. If the panel's branch circuits expect a C-curve (higher inrush tolerance, e.g. for small motors), swapping to a B-curve may cause nuisance tripping on startup. Otherwise the mechanical fit is identical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY7206-6","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/5SY7206-6 when reusing this data.
