EL1 EARTH LEAKAGE PROTECTION RELAY
The EL1 Earth Leakage protection relay is the most advanced Earth Leakage protection on the market to date. The EL1 measures true RMS (harmonic immune) sensitive earth leakage accurately from 25mA to 10.0A. Auto earth leakage test, alarm and trip outputs are available with internal power backup to keep led indicators active for up to 3 hours after a trip (power down). Non volatile trip state will remain active even after a long power down. Three different trip levels with trip delays are available for the three states (STANDBY, STARTUP and RUN).
