The Siemens 5SL6604-7CC is a 3+N-pole miniature circuit breaker (MCB) rated for 400 V with a 6 kA breaking capacity, C-curve trip characteristic, and 4 A rated current. The C-curve trips between 5 and 10 times rated current, so this 4 A breaker will clear a fault between 20 A and 40 A — appropriate for circuits where the load has a modest start-up surge but not the high inrush of a large motor or transformer.
RoHS compliance is confirmed since 01-06-13, and REACH candidate-list information is available on request. The product class is B — return restricted.
