Acrel ASJ10-LD1C Earth Leakage Relay

ASJ10 series intelligent residual current relays are suitable for the occasions where residual current needs to be detected and ground fault protection of electrical lines is required. It is used in conjunction with low-voltage circuit breakers or contactors to protect electrical lines from ground faults and prevent electrical leakage caused by leakage current.
