Siemens 5SY6202-7 SENTRON 2P Miniature Circuit Breaker C 2A 6kA

The Siemens 5SY6202-7 is a SENTRON 2-pole miniature circuit breaker rated 2 A on a C tripping characteristic. It provides combined overload and short-circuit protection on both poles, suitable for single-phase + neutral or two-line circuits up to 230/400 V AC. Rated 6 kA per EN 60898-1, 30 kA per IEC 60947-2, and 5 kA per UL 1077.
