Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) matches the mechanical shock profile of traction and under-car equipment. Fastens via the quick-assembly system; mountable in any position. IP20 with connected conductors, so it is intended for a protected enclosure, not open-rack. Sealable terminals and halogen-free / silicon-free construction are specified.","metaTitle":"Siemens 5SY5214-7CC11 SENTRON MCB, 2P C 0.3A, 440V DC Railwa","metaDescription":"Siemens 5SY5214-7CC11 SENTRON miniature circuit breaker, 2-pole, C-curve, 0.3 A, 440 V DC, 10 kA breaking capacity per IEC 60947-2.
