IP20 with conductors connected, so it's fine inside a closed panel but not for wet locations. ## Thermal derating and environment Rated 4 A at 35 °C ambient. Derate to 3.81 A at 40 °C, 3.71 A at 45 °C, 3.61 A at 50 °C, and 3.51 A at 55 °C. Operating range is -40 to 75 °C, so cold storage or outdoor enclosures are fine. Humidity limit: 95 % up to 55 °C, tapering to 35 % at 75 °C.","metaTitle":"Siemens SENTRON 5SY4304-6CC MCB, 3P, B-Curve, 4 A, 10 kA","metaDescription":"Siemens SENTRON 5SY4304-6CC miniature circuit breaker, 3-pole, B-curve, 4 A rated. 10 kA breaking capacity per EN 60898, 5 kA per UL 1077.
