That dual rating means it covers residential/commercial panel duty and industrial feeder applications where higher fault current is expected. The D curve handles inrush from motor and transformer loads — holds through the startup spike, trips on sustained overload. Temperature derating is built in: at 40 °C ambient it's 1.52 A, at 50 °C it's 1.44 A, at 60 °C it's 1.36 A. If the panel runs hot, factor that down before locking the BOM. Width is 18 mm — one modular unit — so it snaps into a standard DIN rail and occupies a single slot. IP20 with connected conductors is the standard protection — fine inside a closed cabinet, not for washdown zones. Lifecycle stage is current — Siemens still builds this order code. No NRND flag, no last-time-buy notice to chase. Compliance documentation covers IEC 60898-1, IEC 60947-2, and UL1077. The UL1077 listing means it's recognized as a supplementary protector in North American panels, not a branch-circuit rated device — that distinction matters for the local code inspector.","metaTitle":"Siemens 5SY4115-8 SENTRON MCB, 1.6 A, D Curve, 1P, 10 kA","metaDescription":"Siemens 5SY4115-8 SENTRON miniature circuit breaker, 1.6 A, D tripping characteristic, 1-pole, 10 kA (EN 60898) / 35 kA (IEC 60947-2).

The difference is the current rating — 5SY4140-7 is higher amperage. If the circuit load is within 1.6 A, the 5SY4115-8 swaps in without panel modifications."},{"question":"What compliance documentation does this brand provide for 5SY4115-8?","answer":"The breaker is certified to IEC 60898-1, IEC 60947-2, and UL1077.
