Siemens 5SY6116-7 SENTRON 1P Miniature Circuit Breaker C 16A 6kA

The Siemens 5SY6116-7 is a SENTRON 1-pole miniature circuit breaker rated 16 A on a C tripping characteristic. It provides combined overload and short-circuit protection on phase conductors in single- or multi-phase distribution circuits at up to 230/400 V AC. Rated 6 kA per EN 60898-1 (household/commercial), 15 kA per IEC 60947-2 (industrial), and 5 kA per UL 1077.
