In dc connectors with large inrush current you can add a resistor that make connection before the conductor to prevent the spark.
There does not seem to be a similar thing for dc breaker and for a good reason I assume. But what is that reason? A dc breaker that breaks dc line first while still having a resistor in line until you fully break the connection should raise voltage up to close to open voltage values and when that breaks no arc happens. I know that even ac breakers can break very high dc voltages no problem as long as they are in close to max open voltage but if they anywhere near short circuit they arc like crazy.
Or?
