The Siemens 5SY5125-7CC12 is a 1-pole miniature circuit breaker from the 5SY5 series, rated C25 (25 A C-curve) with a 220V DC breaking capacity of 10 kA. The 220V DC rating is the critical parameter here — this is a DC-rated MCB, not a standard AC-only device, so it can safely interrupt DC arcs on battery banks, DC bus supplies, or solar combiner boxes. The 10 kA interrupting capacity at 220V DC gives the fault-current headroom needed for industrial DC distribution.
