Features
  • Earth continuity protection

  • Resistive termination unit for greater noise tolerance

  • Resistance dependent trip characteristic

  • Robust pilot noise rejection

  • Selectable trip resistance from 15Ω to 90Ω in 5Ω steps

  • DIN rail mounted

  • External reset

  • AC or DC supply operation

  • LED status indicators



Applications
  • Required accessory part for the ECM3

  • The ECM3 has been designed to provide earth continuity protection for cables containing pilot cores

  • In practical applications, environmental factors often prevent an earth continuity protection system from complying with both requirements of AS/NZS 2081 and AS/NZS 4871

  • Affecting factors can include coupled noise onto the pilot of the cable, variation in the resistance of the pilot cable due to temperature, and the overall length of the cable

  • The introduction of the dynamic trip response characteristic allows an electrical protection system incorporating an ECM3 to maintain a much lower touch voltage under earth fault conditions without any degradation of reliability or the introduction of nuisance tripping
