The Siemens 5SY5204-7CC12 is a 2-pole miniature circuit breaker from the 5SY5 series, carrying a C4 tripping characteristic and rated for 440V DC with a 10kA breaking capacity. The C4 curve means it tolerates brief inrush currents up to 4–7 times the rated current before tripping — suited for motor-starter or transformer-coupled DC loads where a B curve would nuisance-trip.
