Basler ES-25-1FA1N0N0 Relay

ES-25 sync-check relays monitor two ac circuits and provide a contact output when the two circuits are synchronized. Typical application of the ES-25 involves supervision of an automatic or manual circuit breaker closing scheme. The ES-25 offers true sync-check protection by monitoring the phase displacement and voltage difference between two sources of single, dual, or three phase systems.
