The Siemens SENTRON 5SL4110-7CC is a 1-pole miniature circuit breaker with a C tripping characteristic, rated 10 A and a breaking capacity of 10 kA according to EN 60898 at 400 V AC. Rated for single-phase operation up to 250 V AC and multi-phase up to 440 V AC, it handles both 230/400 V split-phase and 400 V three-phase networks. The supply frequency is 50/60 Hz, covering both mains standards globally. For DC circuits, the maximum rated voltage is 72 V — useful for control circuits but not for high-voltage DC bus protection.
Depth is 76 mm, height 90 mm, width 18 mm (1 MWU). The terminals accept supplementary devices (shunt trip, auxiliary contacts, alarm switch) for remote signaling or emergency off.
The 5SL4363-7 is the 3-pole version of the same breaker family — same depth (76 mm), height (90 mm), C-curve, 10 kA breaking capacity per both EN 60898 and IEC 60947-2, and same 400 V AC rating. The key difference: the 3-pole unit occupies 3 MWU (54 mm wide) and dissipates 5 W per pole in hot state. If your panel was laid out for 5SL4363-7, the 1-pole 5SL4110-7CC will not drop in without rewiring — the pole count and busbar arrangement are different. But within a single-phase branch circuit, the 5SL4110-7CC is the correct 1-pole choice.
