Can RCCB type B use with DC voltage?

For RCCB, we do not have a full-DC operated RCCB.

the RCCB B type cannot be used in DC distribution network. This device is for distribution network with frequency 50 Hz.
As it is Type B, it protects also against DC residual currents generated e.g. by variable speed drives, battery chargers and inverters, backed-up power supplies.
However, it cannot be used in DC distribution network.

So we cannot purpose RCCB for DC network.
