The Siemens 5SL4615-7CC is a 3+N-pole miniature circuit breaker rated 400 V with a 10 kA breaking capacity and a C-curve trip characteristic at 1.6 A. This is the part you spec into a 3-phase + neutral distribution board when you need overcurrent and short-circuit protection for a small lighting or control circuit drawing 1.6 A per phase. The C-curve (5–10× In magnetic trip) suits moderate inrush loads like contactor coils or small transformers where a B-curve would nuisance-trip on startup.
Snap-on DIN rail mount, 3+N-pole width (4 modules at 18 mm each). The 10 kA breaking capacity at 400 V gives adequate fault-clearing headroom for most commercial panelboards — verify the upstream SCCR if the panel is rated higher. Terminal capacity accepts 1–25 mm² copper; torque to 2.5 Nm per the nameplate.
