For motor-starting or heavy transformer loads you would step up to a C or D curve; this one is sized for the clean-switching side of the panel. ## Survives the nacelle — temperature and vibration range Rated from -40 °C to 75 °C ambient, with humidity derating above 55 °C (95 % RH at 55 °C, dropping to 35 % at 75 °C). That covers the inside of a turbine nacelle in winter shutdown or summer solar load — no up-tower swaps for thermal stress. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz. That is the shake a turbine gearbox and generator throw into the control cabinet. The 5SY5110-6 takes it without nuisance tripping or contact bounce — a spec that matters when the breaker is mounted on the same plate as the pitch-drive contactors. Halogen-free and silicon-free construction, which matters in sealed offshore cabinets where outgassing can fog optics or corrode silver contacts. Compliance documentation covers IEC/EN 60898-2 and UL1077. The UL listing means it is accepted for US and Canadian branch-circuit supplementary protection — not a full UL 489 breaker, but the correct class for control-panel overcurrent protection. RoHS, REACH, and CE declarations are standard with the SENTRON series; the manufacturer provides them on request. Width: 18 mm (one modular unit). Height: 90 mm. Quick-assembly fastening system — snaps onto DIN rail without tools, and the combined terminals accept both ferrule and pin terminals for stranded conductors.","metaTitle":"Siemens 5SY5110-6 SENTRON MCB, B-Curve 1P, 10kA IEC, UL1077","metaDescription":"Siemens 5SY5110-6 SENTRON miniature circuit breaker, 1-pole B-curve, 10 kA per IEC/EN 60898-2, UL1077 listed. -40 to 75 °C, vibration rated.
