The Siemens SENTRON 5SY4350-6KK11 is a 3-pole miniature circuit breaker with a B tripping characteristic, rated 10 kA interrupting capacity per EN 60898-1 and 15 kA per IEC 60947-2 at 400 V AC. The dual rating means it meets both the domestic-standard (EN 60898-1) and industrial-standard (IEC 60947-2) SCCR requirements, giving it flexibility for panel builds that need to satisfy either code.
