The Siemens 5SL6340-6CC is a 3-pole miniature circuit breaker from the SENTRON 5SL6 series, rated 40 A with a B-trip curve and a 6 kA breaking capacity at 400 V AC. At 6 kA SCCR it handles fault currents up to that level on a 400 V line, which covers most commercial and light industrial panelboards; for heavy industrial mains with higher available fault current you step up to the 5SL7 series with 10 kA or the 5SL8 at 15 kA.
