The SENTRON 5SY series is a mature, widely specified platform; PCNs are rare, but if a BOM freeze requires assurance, the manufacturer's standard documentation package (declaration of conformity, CE, RoHS, REACH) is available on request. ## Panel integration and environmental limits Snap-on mounting to DIN rail, any position. Ambient temperature range -40 °C to 75 °C, with humidity derating above 55 °C (max 95% RH at 55 °C, declining to 35% at 75 °C). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — adequate for most industrial machinery but not for direct engine-mount applications.","metaTitle":"Siemens SENTRON 5SY5202-7CC MCB, 2A C-Curve 2P DC 440V 10kA","metaDescription":"Siemens SENTRON 5SY5202-7CC miniature circuit breaker, 2A, C-curve, 2-pole, 440 V DC, 10 kA breaking capacity per IEC 60947-2.

The functional difference is the tripping curve: 5SY5202-6 is a B-curve (faster trip on inrush), while this is a C-curve (handles higher inrush before tripping). If the original design assumed B-curve coordination, swapping to C-curve may change selective coordination with upstream breakers.
