Rated breaking capacity is 70 kA per IEC 60947-2 at AC, and 15 kA at DC per the same standard. Pollution degree 3, overvoltage category III — rated for fixed installations in industrial environments where conductive pollution may occur. Ambient temperature range is -40 °C to 75 °C, with derating above 55 °C: at 55 °C the rated current drops to 0.28 A, at 70 °C to 0.29 A (the spec table shows a slight non-monotonicity, but the trend is clear — above 55 °C, derate). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.","metaTitle":"Siemens 5SY8414-7 SENTRON MCB, 4P C 0.3A, 70kA IEC","metaDescription":"Siemens 5SY8414-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 0.3 A rated, 70 kA breaking capacity per IEC 60947-2.
