The Siemens 5SL4216-6CC is a 2-pole miniature circuit breaker rated 400 V with a 10 kA breaking capacity, B-curve trip characteristic, and 16 A rated current. This is the standard MCB for branch-circuit protection in Siemens distribution boards — the B-curve trips between 3 and 5 times rated current, making it a fit for resistive and general-purpose loads where inrush is modest. The 10 kA interrupting rating at 400 V means it can safely clear a fault up to that level without upstream fuses needing to coordinate, which simplifies panel design in commercial and light industrial installations.
