The Siemens 5SL6203-6CC is a 2-pole miniature circuit breaker rated 400 V with a 6 kA breaking capacity and a B tripping characteristic at 3 A. The B-curve means it trips between 3 and 5 times rated current (9–15 A) — standard for protecting lighting and general-purpose circuits where inrush is low. The 6 kA short-circuit capacity at 400 V is sufficient for most residential and light commercial distribution boards; for industrial panels with higher fault current, you'd step up to a 10 kA or 15 kA frame.
