Is there any MCB's for DC supply
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 “
