The Siemens 5SL6614-8CC is a 3+N-pole miniature circuit breaker rated at 400 V with a 6 kA breaking capacity and a D-trip curve at 0.3 A. The D-curve means the magnetic trip operates at 10–20× In, making it suitable for loads with high inrush currents — motor starters, small transformers, or lighting ballasts — where a B- or C-curve would nuisance-trip on startup. The 6 kA interrupting rating at 400 V covers most commercial and light industrial panelboard fault levels; selectivity with upstream devices should be verified against the manufacturer's coordination tables.
