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.","metaTitle":"Siemens 5SY5263-7CC12 MCB 440V DC 10kA 2P C63","metaDescription":"Siemens 5SY5263-7CC12 MCB, 2-pole C63, 440V DC, 10kA breaking capacity.
