The Siemens 5SY5263-7CC12 is a 2-pole miniature circuit breaker from the 5SY5 series, rated C63 with a 10kA breaking capacity at 440V DC. This is a DC-rated MCB, not an AC unit — the arc extinction and contact gap are designed for direct current, where the arc does not self-extinguish at zero crossing. For a panel builder or MRO planner, the 440V DC rating covers common 400V DC bus voltages in solar string combiners, battery racks, or UPS distribution.
