At 40 °C it derates to 30.5 A, at 45 °C to 29.7 A, at 50 °C to 28.9 A, and at 55 °C to 28.06 A. The operating range spans -40 to 75 °C, with humidity limits of 95% up to 55 °C, tapering to 35% at 75 °C. The breaker carries IEC/EN 60898 certification for the 6 kA rating and UL 1077 / CSA C22.2 No. 235 for the 5 kA rating, covering installations under North American and IEC frameworks. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — adequate for machine-mounted panels on pumps, compressors, and conveyors. The energy limitation class is 3, meaning it limits let-through energy to a level that protects downstream components under fault conditions.","metaTitle":"Siemens 5SY6432-7CC SENTRON MCB, 4P, 32A, C-Curve, 6kA","metaDescription":"Siemens SENTRON 5SY6432-7CC miniature circuit breaker, 4-pole, 32 A, C characteristic, 6 kA breaking capacity per EN 60898.
