The EFR-63 Earth Fault Relay is a monitoring device designed to detect earth fault currents in 1Ø-2W, 3Ø-3W, and 3Ø-4W electrical systems. It operates with a rated input current of 5 Amp (supplied via CBCT or CT) and allows the EF trip setting to be configured between 10% and 100% of the input range. Key features include a test mode, LED status indication, and both front-key and remote resetting capabilities. The accompanying instructions detail how to enter parameter setting mode, adjust values such as delay time, and provide essential safety warnings regarding the risk of electric shock during installation and wiring.
