ABB Residual Current Circuit Breakers (RCCB)
Jiahong offers ABB residual current circuit breakers (RCCBs) for earth-leakage protection in residential, commercial, and industrial installations. The right RCCB depends on the type of residual current to be detected, the required sensitivity, and the installation design. If you are replacing an existing device, its product marking and pole configuration provide a useful starting point for identifying a suitable option.
