The Siemens SENTRON 5SL6116-7CC is a 1-pole miniature circuit breaker rated 16 A with C-curve tripping characteristic and a 6 kA breaking capacity according to EN 60898.
The 6 kA breaking capacity at 230/400 V AC per EN 60898 covers most building-installation fault levels; for higher prospective short-circuit currents (e.g., 10 kA industrial boards), you step up to the SENTRON 5SL series variants rated per IEC 60947-2. Rated for single-phase operation up to 250 V AC and multi-phase up to 440 V AC, the 1-pole design protects one phase leg.
