Residual Current Circuit Breaker RCCB

RCCB Residual Current Circuit Breaker is an automatically operating device designed for electrical switches. Its main function is to protect the circuit from conditions such as overload or short circuit that may cause damage. It detects faults and immediately interrupts the current flow if a fault occurs.RCCB Unlike traditional fuses, which need to be replaced after an overload or short circuit, the RCCB can be reset manually or automatically to restore normal operation.
