EOCR-PMZ Built-in Panel dan EOCR-PFZ Embedded Panel

  • Current system function, which automatically displays 3-phase current and leakage current in circulation every 5 seconds
  • Can be switched from auto circulation display mode to manual circulation mode with the touch of a button, allowing focused display on a certain element (one specific phase out of 3 phases or leakage current)
  • Contains the over current/under current/earth fault/current signal output function in a single EOCR
  • Wide range of use: 0.1~3600A – wide range: 0.5~60A; for 5 holes: 0.1~2.0A; with the use of an external CT: 1~3600A
  • Easily identifiable characters and numbers displaying trip causes
  • The last trip causes remembers up to the 3 most recent trip causes and the current at the time of the trips, and checks the operation even during the recovery of electricity after a power outage
  • Includes a timer function for checking total operation time and to provide a reminder of maintenance tasks, such as bearing replacement
  • Has a bar graph which helps the manager to set over current conveniently and to check the motor load factor
  • Has a transducer function (4~20mA current signal output) for easy and focused management
  • For over current operation characteristics, select from Definite, Inverse, and Thermal Inverse
  • Earth fault (leakage) current detection: zero-phase current detection method
  • For earth fault current operation characteristic, apply either Definite or Inverse
  • Over Current Protection Characteristics
    – Thermal Memory Protection (“th”): When Inverse is applied, the cumulative calculation value of the heat generated during the motor’s  operation is remembered in order to be protected directly by the hot curve instead of the cold curve. (Automatically resets 20 minutes after the motor stop)
    – Non-thermal Memory Protection (“ln”): When Inverse is applied, it is protected by the cold curve if the motor has started, and by the hot curve during normal operation
  • Removable EOCR allows its use in the terminal type or the hole type (removable terminal strip)
