The Siemens 5SL6620-7BB is a miniature circuit breaker rated 400 V with a 6 kA breaking capacity, configured as 3+N-pole, C-curve, 20 A, in the Italy version. The C-curve characteristic means it trips at 5 to 10 times rated current, suited for general-purpose loads like lighting and small motor circuits where inrush is moderate. The 6 kA breaking capacity at 400 V determines the maximum fault current it can safely interrupt without upstream damage — sized for typical sub-distribution boards in commercial and light industrial panels.
