The Siemens 5SY5114-7CC12 is a 1-pole miniature circuit breaker from the 5SY5 series, rated C0.3A with a 220V DC breaking capacity of 10kA.
Deployment context
Snap-on DIN rail mount for a standard 18mm module width, so it fits alongside other 5SY series breakers in a distribution sub-panel or control cabinet. The 220V DC rating makes it a natural fit for DC link protection in drive systems or for isolating control power supplies in a 24V DC panel where the bus voltage is stepped up.
