It also carries a maximum DC rating of 72 V. The terminals accept solid or stranded copper from 0.75 mm² up to 35 mm², with a tightening torque of 2.5 to 3.5 N·m. Both top and bottom terminals are combined (busbar-ready), and the unit is sealable for anti-tamper applications. The breaker is designed for railway applications and for mechanical engineering/industry use. Derating applies above 55 °C per the surrounding temperature influence table (max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C). ## Installation & Integration Panel integration is straightforward: the 18 mm width fits one standard module position on a DIN rail. Touch protection is built in.","metaTitle":"Siemens 5SY4150-8CC11 SENTRON MCB, 1P D 50 A 10 kA","metaDescription":"Siemens 5SY4150-8CC11 SENTRON miniature circuit breaker, 1-pole, D-curve, 50 A, 10 kA breaking capacity per EN 60898, 400 V AC, 72 V DC, IP20, halogen-free.
