Residual Current Device (RCD) 2p 40A 100mA type AC 6kA УЗО-03 DEKraft 14218DEK

Residual Current Circuit Breaker (RCCB) series UZO-03 Dekraft; 2P; rated current 40 A; rated differential current 100 mA; electromechanical; differential trip unit type - AC; for DIN-rail. RCDs are installed in networks with voltages up to 400 V AC. RCDs are used to protect electrical installations from the risk of fire due to current leakage. The design of the devices allows them to operate even at low temperatures. During assembly, the residual current circuit breaker (RCD) and the circuit breaker (for RCD 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.
