The Siemens 5SL6601-6CC is a 3+N-pole miniature circuit breaker rated 400 V with a 6 kA breaking capacity, B-curve trip characteristic, and 1 A rated current. This is the SENTRON 5SL6 series basic device — the standard MCB for panelboard and distribution board protection in commercial and light industrial installations where the B-curve (3–5× In magnetic trip) protects cable runs and resistive loads against short-circuit and overload.
The 3+N-pole format occupies four modular width units (4 × 18 mm = 72 mm) in the distribution board. Rated for 400 V between phases, the 6 kA breaking capacity covers most commercial sub-distribution fault levels; verify the prospective short-circuit current at the installation point stays under 6 kA.
REACH candidate-list information is available on request. The packaging unit is one piece, sold individually.
