The D-curve (10–20 × In magnetic trip) is sized for loads with a high inrush-to-running ratio: small motors, solenoid banks, control transformers. At 2 A, it protects a branch circuit drawing roughly 480 VA on a 230/400 V system. Pollution degree 3, overvoltage category III — rated for fixed-installation industrial environments where conductive pollution or transient overvoltages from the mains are expected. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) confirms it can ride through typical machine vibration without nuisance tripping. Operating temperature range -40 °C to 75 °C, with humidity derating above 55 °C (max 95% RH at 55 °C, tapering to 35% at 75 °C).","metaTitle":"Siemens 5SY7202-8CC SENTRON MCB, 2-pole D 2A, 400V AC, 50kA","metaDescription":"Siemens 5SY7202-8CC SENTRON miniature circuit breaker, 2-pole, D-curve, 2A, 400V AC, 50kA IEC breaking capacity.
