Rccb Circuit Breaker Rating. This is used in case of a single phase supply connection that has only a live and a neutral wire. The rccb can operate for the same fault conditions where elcb operates.
Rccb are of two types. The rccb can operate for the same fault conditions where elcb operates.

But its method of operation or fault detection is entirely different from that of elcb. These devices must be used in series with an mcb or fuse which protects them from the potentially damaging thermal and dynamic stresses of any over.
