Its C tripping characteristic (5-10x In) makes it suitable for protecting loads with moderate inrush, such as control transformers or solenoid banks in DC distribution. ## DC Ratings and Thermal Derating Rated current at 40 °C is 0.46 A, derating to 0.38 A at 60 °C and 0.3 A at 75 °C. For a DC bus running at 60 °C ambient, expect the continuous current capacity to drop to 0.38 A. ## Railway and Environmental Qualification Designed for railway applications per the product design designation. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. Halogen-free and silicon-free construction. Degree of pollution 3, overvoltage category III. Polarity must be observed on the supply cord.","metaTitle":"Siemens 5SY5205-7CC11 SENTRON MCB, 2-Pole DC, 440V, 10kA, C-","metaDescription":"Siemens 5SY5205-7CC11 SENTRON miniature circuit breaker, 2-pole DC, rated 440V, 10kA breaking capacity per IEC 60947-2.
