RCD 4P 40A 30mA type AC 6kA UZO-03 DEKraft 14235DEK

Residual current device series UZO-03 Dekraft; 4P; rated current 40 A; rated residual current 30 mA; electromechanical; differential trip type - AC; for DIN rail. RCDs are installed in AC networks with voltage up to 400 V. RCDs 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. During assembly, the residual current device (RCD) and the circuit breaker (to protect the RCD) 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.
