Difference between RCCB and ELCB/RCBO

The function of RCCB is testing ground fault current when detected Fault current  leakage current is more than the leakage when the tripping current RCCBs will loop Disconnect. It is important to note RCCBs does not have magnetic protection namely  and short circuit protection.

ELCB/RCBO function:Protection of short-circuit protection,excessive protection and Leakage protection.
