Two modular-width units (36 mm wide) snap onto standard DIN rail. Mounting position is any orientation. Combined top and bottom terminals — wire entry from either direction without flipping the breaker. Sealable cover option for tamper-proofing in accessible panels. IP20 with connected conductors, so it lives inside a closed enclosure, not exposed to washdown. ## Temperature derating The 8 A rating holds at 35 °C ambient. At 40 °C it derates to 7.1 A, at 45 °C to 6.6 A, at 50 °C to 6.06 A, and at 55 °C to 5.47 A. Humidity tolerance: 95% up to 55 °C, derating to 35% at 75 °C. Halogen-free and silicon-free construction. Product designation per EN 61346-2 and IEC 81346-2 is function code F. Suitability marked for mechanical engineering and machine manufacture. The part carries no neutral conductor switching — two poles both switch phase/DC lines, no switched neutral.","metaTitle":"Siemens 5SY5208-7CC SENTRON MCB, 2P C-8A, 10kA DC","metaDescription":"Siemens 5SY5208-7CC SENTRON miniature circuit breaker, 2-pole, C-curve 8 A, 10 kA DC breaking capacity at 440 V.
