The B-curve trips between 3 and 5 times rated current, so a 2 A unit holds through inrush from a small DC motor or capacitive load but clears a 6–10 A fault within the instantaneous band. Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating above 55 °C: 95% RH up to 55 °C, 55% RH to 70 °C, and 35% RH to 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — it holds up on a machine frame or in a mobile substation.","metaTitle":"Siemens 5SY5202-6CC SENTRON MCB, 2A B-Curve, 2-Pole DC 440V","metaDescription":"Siemens SENTRON 5SY5202-6CC miniature circuit breaker, 2 A, B characteristic, 2-pole DC, 440 V, 10 kA interrupting rating per IEC 60947-2.
