WebUnlike on an earth leakage breaker, there is no interruption performed and there is only an earth leakage detection function. Detection of the earth leakage is performed (ZCT) and then a signal is sent when there is earth leakage (relay part). It is used with a combination of a ZCT (zero-phase current transformer) and a relay. WebExamples of protection relays Relays and relay parts Auxiliary relay with mechanical contacts Auxiliary relay, block symbol Static relay with terminals for external auxiliary voltage supply U Relay with make contact, delayed when the relay is energized. Pick-up delay Relay with brake contact, delayed when the relay is deenergized. Drop-out delay
