The Siemens 5SL4650-6CC is a 3+N-pole miniature circuit breaker rated at 400 V with a 10 kA breaking capacity, B-curve trip characteristic, and 50 A current rating — a standard MCB for final-distribution panels in commercial and light-industrial installations. The B-curve trips between 3 and 5 times rated current, suited for resistive and general-purpose loads where inrush is modest. The 10 kA SCCR at 400 V means it safely interrupts fault currents up to that level without requiring an upstream current-limiting device in most panelboard configurations.
Sourcing and fit
The 5SL4650-6CC snaps onto standard DIN rail, occupying a 4-module width for the 3+N-pole configuration. It is part of the Siemens 5SL4 Basic Devices family, which shares a common footprint and busbar system across the range. For a BOM line requiring a 50 A, B-curve, 3+N MCB at 400 V with 10 kA breaking capacity, this is the direct Siemens order code — no cross-reference needed.
