Earth Leakage Relay 770X
Earth Leakage Relay with variable earth leakage current and trip time settings, external CBCT sensing, reset and test facilities, and healthy and trip LED indication.
Continuous Earth Leakage Monitoring
The SYCON 770X Earth Leakage Relay continuously monitors earth leakage current using an externally mounted CBCT (Core Balance Current Transformer). Current-carrying cables from either single-phase or three-phase supplies are passed through the CBCT. The relay detects the earth leakage current and trips the connected system when the set current and set tripping time are reached.
