It is explicitly designed for railway applications, meeting the vibration resistance of IEC 60068-2-6 (50 m/s² at 25–150 Hz) and the environmental range of -40 °C to 75 °C. The 5SY4316-8CC11 occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position and uses a quick-assembly fastening system. ## Thermal derating and operating conditions The breaker's ambient temperature range is -40 °C to 75 °C, but the surrounding humidity must be derated above 55 °C: max 95% RH up to 55 °C, then 55% RH up to 70 °C, and 35% RH up to 75 °C.","metaTitle":"Siemens 5SY4316-8CC11 SENTRON MCB, 3P D 16A 10kA 400V","metaDescription":"Siemens 5SY4316-8CC11 SENTRON miniature circuit breaker, 3-pole, D-curve, 16A, 10kA breaking capacity at 400V AC.
