Dear ;

 

Normally we can use the MCB's for ” DC supply ” but we should take into account the necessary information determinedby the manufacturers for this application, noting that the most important points are :

1 – System voltage : determined by the number of poles connected in series.

2 – Short Circuit Current : determined by the manufacturers depending on the ” L/R ” value

3 – Tripping caracteristics :

     – The ” Thermal Protection ” : unchanged

     – The ” Magnetic Protection ” : it will become less sensitive and should be derating by ” √2 “

 

Regards.
