It also carries a UL1077 listing at 5 kA, making it a dual-standard part for panels shipping to both IEC and North American markets. Ambient range spans -40 °C to 75 °C, with derating on humidity: max 95% RH at 55 °C, tapering to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, which suits rotating machinery environments.","metaTitle":"Siemens 5SY8463-7 SENTRON MCB, 4P C-Curve, 25 kA IEC","metaDescription":"Siemens 5SY8463-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 25 kA interrupting capacity at 400 V AC per IEC 60947-2.
