At 40 °C the continuous rating derates to 23.3 A, at 50 °C to 21.45 A — so if your panel ambient runs warm, size the load against the derated number, not the 35 °C headline. ## Panel integration IP20 with connected conductors — fine for enclosed industrial panels, not for wet washdown zones. Rated for ambient temperatures from -40 °C to 75 °C, with humidity limits per the spec (max 95% at 55 °C, derating to 35% at 75 °C). Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz.","metaTitle":"Siemens 5SY5225-7CC SENTRON MCB, 2P C-curve 25 A, 10 kA DC","metaDescription":"Siemens SENTRON 5SY5225-7CC miniature circuit breaker, 2-pole C-curve, rated 25 A at 35 °C, 10 kA DC breaking capacity at 440 V.
