The C-curve (magnetic trip at 5–10× In) handles moderate inrush from DC motors or solenoid valves without nuisance trips. At 440 V DC the breaking capacity is 10 kA; at 500 V DC the maximum operating voltage, the same 10 kA holds per IEC 60947-2. ## Railway-specific construction Designed for railway applications, the breaker meets vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz. Halogen-free and silicon-free construction avoids toxic off-gassing in a tunnel or passenger compartment. Sealable terminals let a maintainer lock the cover after commissioning. Combined top and bottom terminals simplify daisy-chaining in a distribution panel.","metaTitle":"Siemens 5SY5202-7CC11 SENTRON MCB, 2A C-Char DC, 2-Pole, 10k","metaDescription":"Siemens 5SY5202-7CC11 SENTRON miniature circuit breaker, 2A C-trip, 2-pole DC, 10kA breaking capacity at 440V DC.
