Earth Leakage Protection Relay

Earth Leakage Protection, Earth Leakage Protection Relay, Protection Relay, Protective Relays, EL1 Earth Leakage Protection Relay, Earth Leakage ProtectionThe 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).

Features:

  • One true RMS voltage channel (Supply voltage)
  • One true RMS Current channel (Core balance)
  • One 115/250Vac input (Contactor ON / External Reset)
  • Two voltage free relay contacts (Auto test/Alarm and Trip)
  • Sensitive earth leakage protection true RMS
  • Remote controlled Infra red port
  • Internal power backup after trip to indicate last state
  • Three different trip levels
  • Three different trip delays
  • External reset
