The 10 kA breaking capacity per EN 60898 tells you it can safely interrupt a fault current up to 10,000 A at 400 V, which is standard for most industrial sub-distribution panels. ## Where and how it fits Single-pole (1P), 18 mm wide — one width unit on a standard DIN rail. The quick-assembly system and combined terminals top and bottom simplify busbar and outgoing wiring. Conductor cross-section accepts 0.75 to 35 mm² solid or stranded, with a tightening torque of 2.5 to 3.5 N·m. ## Design specifics for railway and industry The 5SY4110-8CC11 is explicitly designed for railway applications (per) and is also marked suitable for mechanical engineering and industry. It's halogen-free and silicon-free, which matters in environments where outgassing can contaminate sensitive contacts or optics. Sealable and touch-protected — the sealable feature lets you lock the toggle position after commissioning, preventing unauthorized switching in safety-critical circuits.","metaTitle":"Siemens 5SY4110-8CC11 SENTRON MCB, 1P D 10 A, 10 kA","metaDescription":"Siemens 5SY4110-8CC11 SENTRON miniature circuit breaker, 1-pole, D-curve, 10 A rated, 10 kA breaking capacity per EN 60898.

The difference is the rating: the 5SY4116-7CV is a 16 A D-curve. If your load is 10 A or less, the 5SY4110-8CC11 is a direct drop-in without rewiring.
