The Siemens 5SL4150-7CC is a 1-pole miniature circuit breaker rated 50 A with a C-trip curve and a 10 kA breaking capacity at 230/400 V. It belongs to the 5SL4 series of Basic Devices, designed for panelboard and distribution board installation protecting branch circuits against overload and short circuit. In a 400 V three-phase panel, a single-pole unit protects one phase leg; for line-to-line or three-phase loads, match with 2-pole or 3-pole 5SL4 siblings in the same rail.
