Residual Current Circuit Breaker (RCCB) 4p 63A 100mA type AC 6kA RCCB-03 DEKraft 14244DEK

Residual current circuit breaker Dekraft UZO-03 series; 4P; rated current 63 A; rated residual current 100 mA; electromechanical; differential trip type - AC; for DIN rail. RCCBs are installed in networks with a voltage of up to 400 V AC. RCCBs are used to protect electrical installations from the risk of fire due to current leakage. The design of the devices allows them to be operated even at low temperatures. When assembling, the residual current circuit breaker (RCCB) and the circuit breaker (for RCCB protection) are installed in series, whereby the rated current of the device must be one step higher — i.e., 20A when installed in series with a 16A circuit breaker, 32A when installed with a 25A circuit breaker.
