It is designed for universal current operation — AC or DC — making it a fit for both standard lighting and control circuits and DC rail applications where polarity must be observed on the supply cord. At 1.6 A, this breaker protects a branch circuit drawing up to that current continuously at 35 °C; above that ambient, the thermal derating table applies (1.52 A at 40 °C, 1.44 A at 50 °C, 1.36 A at 60 °C). The 10 kA breaking capacity at 230/400 V AC per EN 60898 and 10 kA at DC per EN 60898-2 means this breaker can safely interrupt a fault current up to that level without welding its contacts or cascading failure upstream.","metaTitle":"Siemens 5SY5115-7KK11 SENTRON MCB, 1P C 1.6A, 10kA","metaDescription":"Siemens 5SY5115-7KK11 SENTRON miniature circuit breaker, 1-pole, C-curve, 1.6 A, 10 kA breaking capacity, AC/DC rated.
